It builds +on the [Mesos EC2 script](https://github.com/mesos/mesos/wiki/EC2-Scripts) +in Apache Mesos. + +`spark-ec2` is designed to manage multiple named clusters. You can +launch a new cluster (telling the script its size and giving it a name), +shutdown an existing cluster, or log into a cluster. Each cluster is +identified by placing its machines into EC2 security groups whose names +are derived from the name of the cluster. For example, a cluster named +`test` will contain a master node in a security group called +`test-master`, and a number of slave nodes in a security group called +`test-slaves`. The `spark-ec2` script will create these security groups +for you based on the cluster name you request. You can also use them to +identify machines belonging to each cluster in the EC2 Console or +ElasticFox. + +This guide describes how to get set up to run clusters, how to launch +clusters, how to run jobs on them, and how to shut them down. + +Before You Start +================ + +- Create an Amazon EC2 key pair for yourself. This can be done by + logging into your Amazon Web Services account through the [AWS + console](http://aws.amazon.com/console/), clicking Key Pairs on the + left sidebar, and creating and downloading a key. Make sure that you + set the permissions for the private key file to `600` (i.e. only you + can read and write it) so that `ssh` will work. +- Whenever you want to use the `spark-ec2` script, set the environment + variables `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` to your + Amazon EC2 access key ID and secret access key. These can be + obtained from the [AWS homepage](http://aws.amazon.com/) by clicking + Account \> Security Credentials \> Access Credentials. + +Launching a Cluster +=================== + +- Go into the `ec2` directory in the release of Spark you downloaded. +- Run + `./spark-ec2 -k <keypair> -i <key-file> -s <num-slaves> launch <cluster-name>`, + where `<keypair>` is the name of your EC2 key pair (that you gave it + when you created it), `<key-file>` is the private key file for your + key pair, `<num-slaves>` is the number of slave nodes to launch (try + 1 at first), and `<cluster-name>` is the name to give to your + cluster. +- After everything launches, check that Mesos is up and sees all the + slaves by going to the Mesos Web UI link printed at the end of the + script (`http://<master-hostname>:8080`). + +You can also run `./spark-ec2 --help` to see more usage options. The +following options are worth pointing out: + +- `--instance-type=<INSTANCE_TYPE>` can be used to specify an EC2 +instance type to use. For now, the script only supports 64-bit instance +types, and the default type is `m1.large` (which has 2 cores and 7.5 GB +RAM). Refer to the Amazon pages about [EC2 instance +types](http://aws.amazon.com/ec2/instance-types) and [EC2 +pricing](http://aws.amazon.com/ec2/#pricing) for information about other +instance types. +- `--zone=<EC2_ZONE>` can be used to specify an EC2 availability zone +to launch instances in. Sometimes, you will get an error because there +is not enough capacity in one zone, and you should try to launch in +another. This happens mostly with the `m1.large` instance types; +extra-large (both `m1.xlarge` and `c1.xlarge`) instances tend to be more +available. +- `--ebs-vol-size=GB` will attach an EBS volume with a given amount + of space to each node so that you can have a persistent HDFS cluster + on your nodes across cluster restarts (see below). +- If one of your launches fails due to e.g. not having the right +permissions on your private key file, you can run `launch` with the +`--resume` option to restart the setup process on an existing cluster. + +Running Jobs +============ + +- Go into the `ec2` directory in the release of Spark you downloaded. +- Run `./spark-ec2 -k <keypair> -i <key-file> login <cluster-name>` to + SSH into the cluster, where `<keypair>` and `<key-file>` are as + above. (This is just for convenience; you could also use + the EC2 console.) +- To deploy code or data within your cluster, you can log in and use the + provided script `~/mesos-ec2/copy-dir`, which, + given a directory path, RSYNCs it to the same location on all the slaves. +- If your job needs to access large datasets, the fastest way to do + that is to load them from Amazon S3 or an Amazon EBS device into an + instance of the Hadoop Distributed File System (HDFS) on your nodes. + The `spark-ec2` script already sets up a HDFS instance for you. It's + installed in `/root/ephemeral-hdfs`, and can be accessed using the + `bin/hadoop` script in that directory. Note that the data in this + HDFS goes away when you stop and restart a machine. +- There is also a *persistent HDFS* instance in + `/root/presistent-hdfs` that will keep data across cluster restarts. + Typically each node has relatively little space of persistent data + (about 3 GB), but you can use the `--ebs-vol-size` option to + `spark-ec2` to attach a persistent EBS volume to each node for + storing the persistent HDFS. +- Finally, if you get errors while running your jobs, look at the slave's logs + for that job using the Mesos web UI (`http://<master-hostname>:8080`). + +Terminating a Cluster +===================== + +***Note that there is no way to recover data on EC2 nodes after shutting +them down! Make sure you have copied everything important off the nodes +before stopping them.*** + +- Go into the `ec2` directory in the release of Spark you downloaded. +- Run `./spark-ec2 destroy <cluster-name>`. + +Pausing and Restarting Clusters +=============================== + +The `spark-ec2` script also supports pausing a cluster. In this case, +the VMs are stopped but not terminated, so they +***lose all data on ephemeral disks*** but keep the data in their +root partitions and their `persistent-hdfs`. Stopped machines will not +cost you any EC2 cycles, but ***will*** continue to cost money for EBS +storage. + +- To stop one of your clusters, go into the `ec2` directory and run +`./spark-ec2 stop <cluster-name>`. +- To restart it later, run +`./spark-ec2 -i <key-file> start <cluster-name>`. +- To ultimately destroy the cluster and stop consuming EBS space, run +`./spark-ec2 destroy <cluster-name>` as described in the previous +section. + +Limitations +=========== + +- `spark-ec2` currently only launches machines in the US-East region of EC2. + It should not be hard to make it launch VMs in other zones, but you will need + to create your own AMIs in them. +- Support for "cluster compute" nodes is limited -- there's no way to specify a + locality group. However, you can launch slave nodes in your `<clusterName>-slaves` + group manually and then use `spark-ec2 launch --resume` to start a cluster with + them. +- Support for spot instances is limited. + +If you have a patch or suggestion for one of these limitations, feel free to +[[contribute|Contributing to Spark]] it! diff --git a/docs/README.md b/docs/README.md new file mode 100644 index 0000000000..e2ae05722f --- /dev/null +++ b/docs/README.md @@ -0,0 +1,13 @@ +Welcome to the Spark documentation! + +This readme will walk you through navigating and building the Spark documentation, which is included here with the Spark source code.

Make sure you set it high enough to be able to run your job but lower than the total memory on the machines (leave at least 1 GB for the operating system). + +## Logging Configuration + +Spark uses [[log4j|http://logging.apache.org/log4j/]] for logging. You can configure it by adding a `log4j.properties` file in the `conf` directory. One way to start is to copy the existing `log4j.properties.template` located there. diff --git a/docs/contributing-to-spark.md b/docs/contributing-to-spark.md new file mode 100644 index 0000000000..fc7544887b --- /dev/null +++ b/docs/contributing-to-spark.md @@ -0,0 +1,26 @@ +--- +layout: global +title: How to Contribute to Spark +--- +# Contributing to Spark + +The Spark team welcomes contributions in the form of GitHub pull requests. +Here are a few tips to get your contribution in: + +- Break your work into small, single-purpose patches if possible.

For a tutorial, see + the GitHub guides on [[forking a repo|https://help.github.com/articles/fork-a-repo]] + and [[sending a pull request|https://help.github.com/articles/using-pull-requests]]. +- Follow the style of the existing codebase. Specifically, we use [[standard Scala + style guide|http://docs.scala-lang.org/style/]], but with the following changes: + * Maximum line length of 100 characters. + * Always import packages using absolute paths (e.g. `scala.collection.Map` instead of `collection.Map`). + * No "infix" syntax for methods other than operators. For example, don't write + `table containsKey myKey`; replace it with `table.containsKey(myKey)`. +- Add unit tests to your new code. We use [[ScalaTest|http://www.scalatest.org/]] for + testing.

Scripts +--- +The `spark-ec2` script located in the Spark's `ec2` directory allows you +to launch, manage and shut down Spark clusters on Amazon EC2. It builds +on the [Mesos EC2 script](https://github.com/mesos/mesos/wiki/EC2-Scripts) +in Apache Mesos. + +`spark-ec2` is designed to manage multiple named clusters. You can +launch a new cluster (telling the script its size and giving it a name), +shutdown an existing cluster, or log into a cluster. Each cluster is +identified by placing its machines into EC2 security groups whose names +are derived from the name of the cluster. For example, a cluster named +`test` will contain a master node in a security group called +`test-master`, and a number of slave nodes in a security group called +`test-slaves`. The `spark-ec2` script will create these security groups +for you based on the cluster name you request. You can also use them to +identify machines belonging to each cluster in the EC2 Console or +ElasticFox. + +This guide describes how to get set up to run clusters, how to launch +clusters, how to run jobs on them, and how to shut them down. + +Before You Start +================ + +- Create an Amazon EC2 key pair for yourself. This can be done by + logging into your Amazon Web Services account through the [AWS + console](http://aws.amazon.com/console/), clicking Key Pairs on the + left sidebar, and creating and downloading a key. Make sure that you + set the permissions for the private key file to `600` (i.e. only you + can read and write it) so that `ssh` will work. +- Whenever you want to use the `spark-ec2` script, set the environment + variables `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY` to your + Amazon EC2 access key ID and secret access key. These can be + obtained from the [AWS homepage](http://aws.amazon.com/) by clicking + Account \> Security Credentials \> Access Credentials. + +Launching a Cluster +=================== + +- Go into the `ec2` directory in the release of Spark you downloaded. +- Run + `./spark-ec2 -k <keypair> -i <key-file> -s <num-slaves> launch <cluster-name>`, + where `<keypair>` is the name of your EC2 key pair (that you gave it + when you created it), `<key-file>` is the private key file for your + key pair, `<num-slaves>` is the number of slave nodes to launch (try + 1 at first), and `<cluster-name>` is the name to give to your + cluster. +- After everything launches, check that Mesos is up and sees all the + slaves by going to the Mesos Web UI link printed at the end of the + script (`http://<master-hostname>:8080`). + +You can also run `./spark-ec2 --help` to see more usage options. The +following options are worth pointing out: + +- `--instance-type=<INSTANCE_TYPE>` can be used to specify an EC2 +instance type to use. For now, the script only supports 64-bit instance +types, and the default type is `m1.large` (which has 2 cores and 7.5 GB +RAM). Refer to the Amazon pages about [EC2 instance +types](http://aws.amazon.com/ec2/instance-types) and [EC2 +pricing](http://aws.amazon.com/ec2/#pricing) for information about other +instance types. +- `--zone=<EC2_ZONE>` can be used to specify an EC2 availability zone +to launch instances in. Sometimes, you will get an error because there +is not enough capacity in one zone, and you should try to launch in +another. This happens mostly with the `m1.large` instance types; +extra-large (both `m1.xlarge` and `c1.xlarge`) instances tend to be more +available. +- `--ebs-vol-size=GB` will attach an EBS volume with a given amount + of space to each node so that you can have a persistent HDFS cluster + on your nodes across cluster restarts (see below). +- If one of your launches fails due to e.g. not having the right +permissions on your private key file, you can run `launch` with the +`--resume` option to restart the setup process on an existing cluster. + +Running Jobs +============ + +- Go into the `ec2` directory in the release of Spark you downloaded. +- Run `./spark-ec2 -k <keypair> -i <key-file> login <cluster-name>` to + SSH into the cluster, where `<keypair>` and `<key-file>` are as + above. (This is just for convenience; you could also use + the EC2 console.) +- To deploy code or data within your cluster, you can log in and use the + provided script `~/mesos-ec2/copy-dir`, which, + given a directory path, RSYNCs it to the same location on all the slaves. +- If your job needs to access large datasets, the fastest way to do + that is to load them from Amazon S3 or an Amazon EBS device into an + instance of the Hadoop Distributed File System (HDFS) on your nodes. + The `spark-ec2` script already sets up a HDFS instance for you. It's + installed in `/root/ephemeral-hdfs`, and can be accessed using the + `bin/hadoop` script in that directory. Note that the data in this + HDFS goes away when you stop and restart a machine. +- There is also a *persistent HDFS* instance in + `/root/presistent-hdfs` that will keep data across cluster restarts. + Typically each node has relatively little space of persistent data + (about 3 GB), but you can use the `--ebs-vol-size` option to + `spark-ec2` to attach a persistent EBS volume to each node for + storing the persistent HDFS. +- Finally, if you get errors while running your jobs, look at the slave's logs + for that job using the Mesos web UI (`http://<master-hostname>:8080`). + +Terminating a Cluster +===================== + +***Note that there is no way to recover data on EC2 nodes after shutting +them down! Make sure you have copied everything important off the nodes +before stopping them.*** + +- Go into the `ec2` directory in the release of Spark you downloaded. +- Run `./spark-ec2 destroy <cluster-name>`. + +Pausing and Restarting Clusters +=============================== + +The `spark-ec2` script also supports pausing a cluster. In this case, +the VMs are stopped but not terminated, so they +***lose all data on ephemeral disks*** but keep the data in their +root partitions and their `persistent-hdfs`. Stopped machines will not +cost you any EC2 cycles, but ***will*** continue to cost money for EBS +storage. + +- To stop one of your clusters, go into the `ec2` directory and run +`./spark-ec2 stop <cluster-name>`. +- To restart it later, run +`./spark-ec2 -i <key-file> start <cluster-name>`. +- To ultimately destroy the cluster and stop consuming EBS space, run +`./spark-ec2 destroy <cluster-name>` as described in the previous +section. + +Limitations +=========== + +- `spark-ec2` currently only launches machines in the US-East region of EC2. + It should not be hard to make it launch VMs in other zones, but you will need + to create your own AMIs in them. +- Support for "cluster compute" nodes is limited -- there's no way to specify a + locality group. However, you can launch slave nodes in your `<clusterName>-slaves` + group manually and then use `spark-ec2 launch --resume` to start a cluster with + them. +- Support for spot instances is limited. + +If you have a patch or suggestion for one of these limitations, feel free to +[[contribute|Contributing to Spark]] it! diff --git a/docs/img/glyphicons-halflings-white.png b/docs/img/glyphicons-halflings-white.png Binary files differnew file mode 100755 index 0000000000..3bf6484a29 --- /dev/null +++ b/docs/img/glyphicons-halflings-white.png diff --git a/docs/img/glyphicons-halflings.png b/docs/img/glyphicons-halflings.png Binary files differnew file mode 100755 index 0000000000..a996999320 --- /dev/null +++ b/docs/img/glyphicons-halflings.png diff --git a/docs/index.md b/docs/index.md new file mode 100644 index 0000000000..a1fe3b2e56 --- /dev/null +++ b/docs/index.md @@ -0,0 +1,75 @@ +--- +layout: global +title: Spark - Fast Cluster Computing +--- +# Spark Overview + +Spark is a MapReduce-like cluster computing framework designed to support low-latency iterative jobs and interactive use from an interpreter. It is written in [Scala](http://www.scala-lang.org), a high-level language for the JVM, and exposes a clean language-integrated syntax that makes it easy to write parallel jobs. Spark runs on top of the [Apache Mesos](http://incubator.apache.org/mesos/) cluster manager. + +# Downloading + +Get Spark by checking out the master branch of the Git repository, using `git clone git://github.com/mesos/spark.git`. + +# Building + +Spark requires [Scala 2.9](http://www.scala-lang.org/). +In addition, to run Spark on a cluster, you will need to install [Mesos](http://incubator.apache.org/mesos/), using the steps in +[[Running Spark on Mesos]]. However, if you just want to run Spark on a single machine (possibly using multiple cores), +you do not need Mesos. + +To build and run Spark, you will need to have Scala's `bin` directory in your `PATH`, +or you will need to set the `SCALA_HOME` environment variable to point +to where you've installed Scala. Scala must be accessible through one +of these methods on Mesos slave nodes as well as on the master. + +Spark uses [Simple Build Tool](https://github.com/harrah/xsbt/wiki), which is bundled with it. To compile the code, go into the top-level Spark directory and run + + sbt/sbt compile + +# Testing the Build + +Spark comes with a number of sample programs in the `examples` directory. +To run one of the samples, use `./run <class> <params>` in the top-level Spark directory +(the `run` script sets up the appropriate paths and launches that program). +For example, `./run spark.examples.SparkPi` will run a sample program that estimates Pi. Each of the +examples prints usage help if no params are given. + +Note that all of the sample programs take a `<host>` parameter that is the Mesos master +to connect to. This can be a [Mesos master URL](http://www.github.com/mesos/mesos/wiki), or `local` to run locally with one +thread, or `local[N]` to run locally with N threads. You should start by using `local` for testing. + +Finally, Spark can be used interactively from a modified version of the Scala interpreter that you can start through +`./spark-shell`. This is a great way to learn Spark. + +# A Note About Hadoop + +Spark uses the Hadoop core library to talk to HDFS and other Hadoop-supported +storage systems. Because the HDFS protocol has changed in different versions of +Hadoop, you must build Spark against the same version that your cluster runs. +You can change the version by setting the `HADOOP_VERSION` variable at the top +of `project/SparkBuild.scala`, then rebuilding Spark (`sbt/sbt clean compile`). + +# Where to Go from Here + +* [Spark Programming Guide](/programming-guide.html): how to get started using Spark, and details on the API +* [Running Spark on Amazon EC2](/running-on-amazon-ec2.html): scripts that let you launch a cluster on EC2 in about 5 minutes +* [Running Spark on Mesos](/running-on-mesos.html): instructions on how to deploy to a private cluster +* [Configuration](/configuration.html) +* [Bagel Programming Guide](/bagel-programming-guide.html): implementation of Google's Pregel on Spark +* [Spark Debugger](/spark-debugger.html): experimental work on a debugger for Spark jobs +* [Contributing to Spark](contributing-to-spark.html) + +# Other Resources + +* [Spark Homepage](http://www.spark-project.org) +* [Paper describing the programming model](http://www.cs.berkeley.edu/~matei/papers/2012/nsdi_spark.pdf) +* [Code Examples](http://spark-project.org/examples.html) (more also available in the [examples subfolder](https://github.com/mesos/spark/tree/master/examples/src/main/scala/spark/examples) of the Spark codebase) +* [Mailing List](http://groups.google.com/group/spark-users) + +# Community + +To keep up with Spark development or get help, sign up for the [spark-users mailing list](http://groups.google.com/group/spark-users). + +If you're in the San Francisco Bay Area, there's a regular [Spark meetup](http://www.meetup.com/spark-users/) every few weeks.

The main abstraction Spark provides is a *distributed dataset*, which is a collection of elements partitioned across the nodes of the cluster that can be operated on in parallel. Distributed datasets are created by starting with a file in the Hadoop file system (HDFS) or an existing collection in the driver program and possibly transforming it. Users may also ask Spark to *cache* a dataset in memory, allowing it to be reused efficiently across parallel operations. Finally, distributed datasets automatically recover from node failures. + +A second abstraction in Spark is *shared variables* that can be used in parallel operations. By default, when Spark runs a function in parallel as a set of tasks on different nodes, it ships a copy of each variable used in the function to each task. Sometimes, a variable needs to be shared across tasks, or between tasks and the driver program. Spark supports two types of shared variables: *broadcast variables*, which can be used to cache a value in memory on all nodes, and *accumulators*, which are variables that are only "added" to, such as counters and sums. + +This guide shows each of these features and walks through some samples. It assumes some familiarity with Scala, especially with the syntax for [closures](http://www.scala-lang.org/node/133). Note that Spark can be run interactively through the `spark-shell` interpreter. You might want to do that to follow along! + +# Linking with Spark + +To write a Spark application, you will need to add both Spark and its dependencies to your CLASSPATH. The easiest way to do this is to run `sbt/sbt assembly` to build both Spark and its dependencies into one JAR (`core/target/spark-core-assembly-0.5.0.jar`), then add this to your CLASSPATH. Alternatively, you can publish Spark to the Maven cache on your machine using `sbt/sbt publish-local`. It will be an artifact called `spark-core` under the organization `org.spark-project`. + +In addition, you'll need to import some Spark classes and implicit conversions. Add the following lines at the top of your program: + + import spark.SparkContext + import SparkContext._ + +# Initializing Spark + +The first thing a Spark program must do is to create a `SparkContext` object, which tells Spark how to access a cluster. +This is done through the following constructor: + + new SparkContext(master, jobName, [sparkHome], [jars]) + +The `master` parameter is a string specifying a [Mesos](Running Spark on Mesos) cluster to connect to, or a special "local" string to run in local mode, as described below. `jobName` is a name for your job, which will be shown in the Mesos web UI when running on a cluster. Finally, the last two parameters are needed to deploy your code to a cluster if running on Mesos, as described later. + +In the Spark interpreter, a special interpreter-aware SparkContext is already created for you, in the variable called `sc`. Making your own SparkContext will not work. You can set which master the context connects to using the `MASTER` environment variable. For example, run `MASTER=local[4] ./spark-shell` to run locally with four cores. + +### Master Names + +The master name can be in one of three formats: + +<table class="table"> +<tr><th>Master Name</th><th>Meaning</th></tr> +<tr><td> local </td><td> Run Spark locally with one worker thread (i.e. no parallelism at all). </td></tr> +<tr><td> local[K] </td><td> Run Spark locally with K worker threads (which should be set to the number of cores on your machine). </td></tr> +<tr><td> HOST:PORT </td><td> Connect Spark to the given <a href="https://github.com/mesos/spark/wiki/Running-spark-on-mesos">Mesos</a> master to run on a cluster. The host parameter is the hostname of the Mesos master. The port must be whichever one the master is configured to use, which is 5050 by default. +<br /><br /> +<strong>NOTE:</strong> In earlier versions of Mesos (the <code>old-mesos</code> branch of Spark), you need to use master@HOST:PORT. +</td></tr> +</table> + +### Deploying to a Cluster + +If you want to run your job on a cluster, you will need to specify the two optional parameters: + +* `sparkHome`: The path at which Spark is installed on your worker machines (it should be the same on all of them). +* `jars`: A list of JAR files on the local machine containing your job's code and any dependencies, which Spark will deploy to all the worker nodes. You'll need to package your job into a set of JARs using your build system. For example, if you're using SBT, the [sbt-assembly](https://github.com/sbt/sbt-assembly) plugin is a good way to make a single JAR with your code and dependencies. + +If some classes will be shared across _all_ your jobs, it's also possible to copy them to the workers manually and set the `SPARK_CLASSPATH` environment variable in `conf/spark-env.sh` to point to them; see [[Configuration]] for details. + + +# Distributed Datasets + +Spark revolves around the concept of a _resilient distributed dataset_ (RDD), which is a fault-tolerant collection of elements that can be operated on in parallel. There are currently two types of RDDs: *parallelized collections*, which take an existing Scala collection and run functions on it in parallel, and *Hadoop datasets*, which run functions on each record of a file in Hadoop distributed file system or any other storage system supported by Hadoop. Both types of RDDs can be operated on through the same methods. + +## Parallelized Collections + +Parallelized collections are created by calling `SparkContext`'s `parallelize` method on an existing Scala collection (a `Seq` object). The elements of the collection are copied to form a distributed dataset that can be operated on in parallel. For example, here is some interpreter output showing how to create a parallel collection from an array: + + scala> val data = Array(1, 2, 3, 4, 5) + data: Array[Int] = Array(1, 2, 3, 4, 5) + + scala> val distData = sc.parallelize(data) + distData: spark.RDD[Int] = spark.ParallelCollection@10d13e3e + +Once created, the distributed dataset (`distData` here) can be operated on in parallel. For example, we might call `distData.reduce(_ + _)` to add up the elements of the array. We describe operations on distributed datasets later on. + +One important parameter for parallel collections is the number of *slices* to cut the dataset into. Spark will run one task for each slice of the cluster. Typically you want 2-4 slices for each CPU in your cluster. Normally, Spark tries to set the number of slices automatically based on your cluster. However, you can also set it manually by passing it as a second parameter to `parallelize` (e.g. `sc.parallelize(data, 10)`). + +## Hadoop Datasets + +Spark can create distributed datasets from any file stored in the Hadoop distributed file system (HDFS) or other storage systems supported by Hadoop (including your local file system, [Amazon S3|http://wiki.apache.org/hadoop/AmazonS3]], Hypertable, HBase, etc). Spark supports text files, [[SequenceFiles](http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/mapred/SequenceFileInputFormat.html), and any other Hadoop InputFormat. + +Text file RDDs can be created using `SparkContext`'s `textFile` method. This method takes an URI for the file (either a local path on the machine, or a `hdfs://`, `s3n://`, `kfs://`, etc URI). Here is an example invocation: + + scala> val distFile = sc.textFile("data.txt") + distFile: spark.RDD[String] = spark.HadoopRDD@1d4cee08 + +Once created, `distFile` can be acted on by dataset operations. For example, we can add up the sizes of all the lines using the `map` and `reduce` operations as follows: `distFile.map(_.size).reduce(_ + _)`. + +The `textFile` method also takes an optional second argument for controlling the number of slices of the file. By default, Spark creates one slice for each block of the file (blocks being 64MB by default in HDFS), but you can also ask for a higher number of slices by passing a larger value. Note that you cannot have fewer slices than blocks. + +For [SequenceFiles](http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/mapred/SequenceFileInputFormat.html), use SparkContext's `sequenceFile[K, V]` method where `K` and `V` are the types of key and values in the file. These should be subclasses of Hadoop's [Writable](http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/io/Writable.html) interface, like [IntWritable](http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/io/IntWritable.html) and [Text](http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/io/Text.html). In addition, Spark allows you to specify native types for a few common Writables; for example, `sequenceFile[Int, String]` will automatically read IntWritables and Texts. + +Finally, for other Hadoop InputFormats, you can use the `SparkContext.hadoopRDD` method, which takes an arbitrary `JobConf` and input format class, key class and value class. Set these the same way you would for a Hadoop job with your input source. + +## Distributed Dataset Operations + +Distributed datasets support two types of operations: *transformations*, which create a new dataset from an existing one, and *actions*, which return a value to the driver program after running a computation on the dataset. For example, `map` is a transformation that passes each dataset element through a function and returns a new distributed dataset representing the results. On the other hand, `reduce` is an action that aggregates all the elements of the dataset using some function and returns the final result to the driver program (although there is also a parallel `reduceByKey` that returns a distributed dataset). + +All transformations in Spark are <i>lazy</i>, in that they do not compute their results right away. Instead, they just remember the transformations applied to some base dataset (e.g. a file). The transformations are only computed when an action requires a result to be returned to the driver program. This design enables Spark to run more efficiently -- for example, we can realize that a dataset created through `map` will be used in a `reduce` and return only the result of the `reduce` to the driver, rather than the larger mapped dataset. + +One important transformation provided by Spark is *caching*. When you cache a distributed dataset, each node stores any slices of it that it computes in memory and reuses them in other actions on that dataset (or datasets derived from it). This allows future actions to be much faster (often by more than 10x). Caching is a key tool for building iterative algorithms with Spark and for interactive use from the interpreter. + +The following tables list the transformations and actions supported: + +### Transformations + +<table class="table"> +<tr><th>Transformation</th><th>Meaning</th></tr> +<tr><td> map(<i>func</i>) </td><td> Return a new distributed dataset formed by passing each element of the source through a function <i>func</i>. </td></tr> +<tr><td> filter(<i>func</i>) </td><td> Return a new dataset formed by selecting those elements of the source on which <i>func</i> returns true. </td></tr> +<tr><td> flatMap(<i>func</i>) </td><td> Similar to map, but each input item can be mapped to 0 or more output items (so <i>func</i> should return a Seq rather than a single item). </td></tr> +<tr><td> sample(<i>withReplacement</i>, <i>frac</i>, <i>seed</i>) </td><td> Sample a fraction <i>frac</i> of the data, with or without replacement, using a given random number seed. </td></tr> +<tr><td> union(otherDataset) </td><td> Return a new dataset that contains the union of the elements in the source dataset and the argument. </td></tr> +<tr><td> groupByKey([numTasks]) </td><td> When called on a dataset of (K, V) pairs, returns a dataset of (K, Seq[V]) pairs. +<strong>Note:</strong> By default, this uses only 8 parallel tasks to do the grouping.

This is usually done for side effects such as updating an accumulator variable (see below) or interacting with external storage systems. </td></tr> +</table> + +### Caching +Calling `cache()` on an RDD asks that it be stored in memory after the first time it is computed. Different partitions of the dataset will be stored on the different cluster nodes that computed them, making subsequent uses of the dataset faster. The cache is fault-tolerant -- if any partition of an RDD is lost, it will be recomputed using the transformations that originally created it. + +# Shared Variables + +Normally, when a function passed to a Spark operation (such as `map` or `reduce`) is executed on a remote cluster node, it works on separate copies of all the variables used in the function. These variables are copied to each machine, and no updates to the variables on the remote machine are propagated back to the driver program. Supporting general, read-write shared variables across tasks would be inefficient. However, Spark does provide two limited types of *shared variables* for two common usage patterns: broadcast variables and accumulators. + +## Broadcast Variables + +Broadcast variables allow the programmer to keep a read-only variable cached on each machine rather than shipping a copy of it with tasks. They can be used, for example, to give every node a copy of a large input dataset in an efficient manner. Spark also attempts to distribute broadcast variables using efficient broadcast algorithms to reduce communication cost. + +Broadcast variables are created from a variable `v` by calling `SparkContext.broadcast(v)`. The broadcast variable is a wrapper around `v`, and its value can be accessed by calling the `value` method. The interpreter session below shows this: + + scala> val broadcastVar = sc.broadcast(Array(1, 2, 3)) + broadcastVar: spark.Broadcast[Array[Int]] = spark.Broadcast(b5c40191-a864-4c7d-b9bf-d87e1a4e787c) + + scala> broadcastVar.value + res0: Array[Int] = Array(1, 2, 3) + +After the broadcast variable is created, it should be used instead of the value `v` in any functions run on the cluster so that `v` is not shipped to the nodes more than once. In addition, the object `v` should not be modified after it is broadcast in order to ensure that all nodes get the same value of the broadcast variable (e.g. if the variable is shipped to a new node later). + +## Accumulators + +Accumulators are variables that are only "added" to through an associative operation and can therefore be efficiently supported in parallel. They can be used to implement counters (as in MapReduce) or sums. Spark natively supports accumulators of type Int and Double, and programmers can add support for new types. + +An accumulator is created from an initial value `v` by calling `SparkContext.accumulator(v)`. Tasks running on the cluster can then add to it using the `+=` operator. However, they cannot read its value. Only the driver program can read the accumulator's value, using its `value` method. + +The interpreter session below shows an accumulator being used to add up the elements of an array: + scala> val accum = sc.accumulator(0) + accum: spark.Accumulator[Int] = 0 + + scala> sc.parallelize(Array(1, 2, 3, 4)).foreach(x => accum += x) + ... + 10/09/29 18:41:08 INFO SparkContext: Tasks finished in 0.317106 s + + scala> accum.value + res2: Int = 10 + +# Where to Go from Here + +You can see some [example Spark programs](http://www.spark-project.org/examples.html) on the Spark website. + +In addition, Spark includes several sample jobs in `examples/src/main/scala`. Some of them have both Spark versions and local (non-parallel) versions, allowing you to see what had to be changed to make the program run on a cluster. You can run them using by passing the class name to the `run` script included in Spark -- for example, `./run spark.examples.SparkPi`. Each example program prints usage help when run without any arguments. diff --git a/docs/running-a-spark-standalone-cluster.md b/docs/running-a-spark-standalone-cluster.md new file mode 100644 index 0000000000..cd1aaf3d6c --- /dev/null +++ b/docs/running-a-spark-standalone-cluster.md @@ -0,0 +1,41 @@ +--- +layout: global +title: Running a Spark Standalone Cluster +--- +**Note**: Standalone mode is only supported on the dev branch right now. + +## Before you Start + +- Download and compile Spark as described in the [README](https://github.com/mesos/spark/wiki). +- If you wish to use the EC2 Scripts (described below), you must have an Amazon AWS Account and an EC2 key pair. + +## Configuration + +In order to run a Spark cluster there are two main points of configuration, the `conf/spark-env.sh` file, and the `conf/slaves` file. the `conf/spark-env.sh` file lets you specify settings for the master and slave instances, such as memory, or port numbers to bind on.

By default, both the master and slaves write their log files to the `logs` in the Spark home directory. + +## Connecting to the Cluster + +To run a job against a standalone cluster, pass a URI of the form `spark://<SPARK_MASTER_IP>:<SPARK_MASTER_PORT>` as the Master's URI when setting up a Spark Context (or using the interactive shell). + +## Spark Web Interface + +In order to allow for easy debugging of your cluster we have provided a simple web interface that described the current state of the cluster and jobs. By default you can access it via `http://<SPARK_MASTER_IP>:8080`, but you can specify a different port number in`conf/spark_env.sh`. + +## EC2 Scripts + +To save you from needing to set up a cluster of Spark machines yourself, we provide a set of scripts that launch Amazon EC2 instances with a preinstalled Spark distribution. These scripts are identical to the [EC2 Mesos Scripts](https://github.com/mesos/spark/wiki/EC2-Scripts), except that you need to execute `ec2/spark-ec2` with the following additional parameters: `--cluster-type standalone -a standalone --user ec2-user`. Note that the Spark version on these machines may not reflect the latest changes, so it may be a good idea to ssh into the machines and merge the latest version from github. diff --git a/docs/running-on-amazon-ec2.md b/docs/running-on-amazon-ec2.md new file mode 100644 index 0000000000..26cf9bd767 --- /dev/null +++ b/docs/running-on-amazon-ec2.md @@ -0,0 +1,29 @@ +--- +layout: global +title: Running Spark on Amazon EC2 +--- +This guide describes how to get Spark running on an EC2 cluster.

Download Mesos 0.9.0 from a [[mirror|http://www.apache.org/dyn/closer.cgi/incubator/mesos/mesos-0.9.0-incubating/]]. +3. Configure Mesos using the `configure` script, passing the location of your `JAVA_HOME` using `--with-java-home`. Mesos comes with "template" configure scripts for different platforms, such as `configure.macosx`, that you can run. See the README file in Mesos for other options. **Note:** If you want to run Mesos without installing it into the default paths on your system (e.g. if you don't have administrative privileges to install it), you should also pass the `--prefix` option to `configure` to tell it where to install. For example, pass `--prefix=/home/user/mesos`. By default the prefix is `/usr/local`. +4. Build Mesos using `make`, and then install it using `make install`. +5. Create a file called `spark-env.sh` in Spark's `conf` directory, by copying `conf/spark-env.sh.template`, and add the following lines in it: + * `export MESOS_NATIVE_LIBRARY=<path to libmesos.so>`. This path is usually `<prefix>/lib/libmesos.so` (where the prefix is `/usr/local` by default). Also, on Mac OS X, the library is called `libmesos.dylib` instead of `.so`. + * `export SCALA_HOME=<path to Scala directory>`. +6. Copy Spark and Mesos to the _same_ paths on all the nodes in the cluster (or, for Mesos, `make install` on every node). +7. Configure Mesos for deployment: + * On your master node, edit `<prefix>/var/mesos/deploy/masters` to list your master and `<prefix>/var/mesos/deploy/slaves` to list the slaves, where `<prefix>` is the prefix where you installed Mesos (`/usr/local` by default). + * On all nodes, edit `<prefix>/var/mesos/deploy/mesos.conf` and add the line `master=HOST:5050`, where HOST is your master node. + * Run `<prefix>/sbin/mesos-start-cluster.sh` on your master to start Mesos. If all goes well, you should see Mesos's web UI on port 8080 of the master machine. + * See Mesos's README file for more information on deploying it. +8. To run a Spark job against the cluster, when you create your `SparkContext`, pass the string `HOST:5050` as the first parameter, where `HOST` is the machine running your Mesos master. In addition, pass the location of Spark on your nodes as the third parameter, and a list of JAR files containing your JAR's code as the fourth (these will automatically get copied to the workers).

Configure Mesos using the `configure` script, passing the location of your `JAVA_HOME` using `--with-java-home`. Mesos comes with "template" configure scripts for different platforms, such as `configure.template.macosx`, so you can just run the one on your platform if it exists. See the [[Mesos wiki|https://github.com/mesos/mesos/wiki]] for other configuration options. +4. Build Mesos using `make`. +5. In Spark's `conf/spark-env.sh` file, add `export MESOS_HOME=<path to Mesos directory>`. If you don't have a `spark-env.sh`, copy `conf/spark-env.sh.template`. You should also set `SCALA_HOME` there if it's not on your system's default path. +6. Copy Spark and Mesos to the _same_ path on all the nodes in the cluster. +7. Configure Mesos for deployment: + * On your master node, edit `MESOS_HOME/conf/masters` to list your master and `MESOS_HOME/conf/slaves` to list the slaves. Also, edit `MESOS_HOME/conf/mesos.conf` and add the line `failover_timeout=1` to change a timeout parameter that is too high by default. + * Run `MESOS_HOME/deploy/start-mesos` to start it up.

It's currently in development, but you can try it out in the [arthur branch](https://github.com/mesos/spark/tree/arthur). + +## Introduction + +From a user's point of view, debugging a general distributed program can be tedious and confusing. Many distributed programs are nondeterministic; their outcome depends on the interleaving between computation and message passing across multiple machines. Also, the fact that a program is running on a cluster of hundreds or thousands of machines means that it's hard to understand the program state and pinpoint the location of problems. + +In order to tame nondeterminism, a distributed debugger has to log a lot of information, imposing a serious performance penalty on the application being debugged. + +But the Spark programming model lets us provide replay debugging for almost zero overhead. Spark programs are a series of RDDs and deterministic transformations, so when debugging a Spark program, we don't have to debug it all at once -- instead, we can debug each transformation individually. Broadly, the debugger lets us do the following two things: + +* Recompute and inspect intermediate RDDs after the program has finished. +* Re-run a particular task in a single-threaded debugger to find exactly what went wrong. + +For deterministic errors, debugging a Spark program is now as easy as debugging a single-threaded one. + +## Approach + +As your Spark program runs, the slaves report key events back to the master -- for example, RDD creations, RDD contents, and uncaught exceptions. (A full list of event types is in [EventLogging.scala](https://github.com/mesos/spark/blob/arthur/core/src/main/scala/spark/EventLogging.scala).) The master logs those events, and you can load the event log into the debugger after your program is done running. + +_A note on nondeterminism:_ For fault recovery, Spark requires RDD transformations (for example, the function passed to `RDD.map`) to be deterministic. The Spark debugger also relies on this property, and it can also warn you if your transformation is nondeterministic. This works by checksumming the contents of each RDD and comparing the checksums from the original execution to the checksums after recomputing the RDD in the debugger. + +## Usage + +### Enabling the event log + +* To turn on event logging for your program, set `$SPARK_JAVA_OPTS` in `conf/spark-env.sh` as follows: + + export SPARK_JAVA_OPTS='-Dspark.arthur.logPath=path/to/event-log' + + where `path/to/event-log` is where you want the event log to go relative to `$SPARK_HOME`. + + **Warning:** If `path/to/event-log` already exists, event logging will be automatically disabled. + +### Loading the event log into the debugger + +1. Run a Spark shell with `MASTER=<i>host</i> ./spark-shell`. +2. Use `EventLogReader` to load the event log as follows: + + spark> val r = new spark.EventLogReader(sc, Some("path/to/event-log")) + r: spark.EventLogReader = spark.EventLogReader@726b37ad + + **Warning:** If the event log doesn't exist or is unreadable, this will silently fail and `r.events` will be empty. + +### Exploring intermediate RDDs + +* Use `r.rdds` to get a list of intermediate RDDs generated during your program's execution. An RDD with id _x_ is located at <code>r.rdds(<i>x</i>)</code>. For example: + + scala> r.rdds + res8: scala.collection.mutable.ArrayBuffer[spark.RDD[_]] = ArrayBuffer(spark.HadoopRDD@fe85adf, spark.MappedRDD@5fa5eea1, spark.MappedRDD@6d5bd16, spark.ShuffledRDD@3a70f2db, spark.FlatMappedValuesRDD@4d5825d6, spark.MappedValuesRDD@561c2c45, spark.CoGroupedRDD@539e922d, spark.MappedValuesRDD@4f8ef33e, spark.FlatMappedRDD@32039440, spark.ShuffledRDD@8fa0f67, spark.MappedValuesRDD@590937cb, spark.CoGroupedRDD@6c2e1e17, spark.MappedValuesRDD@47b9af7d, spark.FlatMappedRDD@6fb05c54, spark.ShuffledRDD@237dc815, spark.MappedValuesRDD@16daece7, spark.CoGroupedRDD@7ef73d69, spark.MappedValuesRDD@19e0f99e, spark.FlatMappedRDD@1240158, spark.ShuffledRDD@62d438fd, spark.MappedValuesRDD@5ae99cbb, spark.FilteredRDD@1f30e79e, spark.MappedRDD@43b64611) + +* Use `r.printRDDs()` to get a formatted list of intermediate RDDs, along with the source location where they were created.

Find the task you want to debug. If the task threw an exception, the `ExceptionEvent` that was created will have a reference to the task. For example: + + spark> val task = r.events.collect { case e: ExceptionEvent => e }.head.task + + Otherwise, look through the list of all tasks in `r.tasks`, or browse tasks by RDD using <code>r.tasksForRDD(<i>rdd</i>)</code>, which returns a list of tasks whose input is the given RDD. + +2. Run the task by calling <code>r.debugTask(<i>taskStageId</i>, <i>taskPartition</i>)</code>. The task should contain these two values; you can extract them as follows: + + val (taskStageId, taskPartition) = task match { + case rt: ResultTask[_, _] => (rt.stageId, rt.partition) + case smt: ShuffleMapTask => (smt.stageId, smt.partition) + case _ => throw new UnsupportedOperationException + }) + + The Spark debugger will launch the task in a separate JVM, but you will see the task's stdout and stderr inline with the Spark shell. If you want to pass custom debugging arguments to the task's JVM (for example, to change the debugging port), set the optional `debugOpts` argument to `r.debugTask`. When `debugOpts` is left unset, it defaults to + + -Xdebug -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=8000 + +3. In another terminal, attach your favorite conventional debugger to the Spark shell. For example, if you want to use jdb, run `jdb -attach 8000`. + +4. Debug the task as you would debug a normal program. For example, to break when an exception is thrown: + + > catch org.xml.sax.SAXParseException + +5. When the task ends, its JVM will quit and control will return to the main Spark shell. To stop it prematurely, you can kill it from the debugger, or interrupt it from the terminal with Ctrl-C. + +### Detecting nondeterminism in your transformations + +When a task gets run more than once, Arthur is able to compare the checksums of the task's output. If they are different, Arthur will insert a `ChecksumEvent` into `r.checksumMismatches` and print a warning like the following: + + 12/04/07 11:42:44 WARN spark.EventLogWriter: Nondeterminism detected in shuffle output on RDD 2, partition 3, output split 0 diff --git a/docs/spark-simple-tutorial.md b/docs/spark-simple-tutorial.md new file mode 100644 index 0000000000..9875de62bd --- /dev/null +++ b/docs/spark-simple-tutorial.md @@ -0,0 +1,41 @@ +--- +layout: global +title: Tutorial - Running a Simple Spark Application +--- + +1.
