| | | | | | | | | | | | | | | | | | failures This includes some minor code clean-up as well. The main change is that small files are not memory mapped.

* SPARK-1619 Launch spark-shell with spark-submitPatrick Wendell2014-04-244-11/+10
| | | | | | | | | | | | | | | This simplifies the shell a bunch and passes all arguments through to spark-submit. There is a tiny incompatibility from 0.9.1 which is that you can't put `-c` _or_ `--cores`, only `--cores`. However, spark-submit will give a good error message in this case, I don't think many people used this, and it's a trivial change for users.

* [SPARK-1592][streaming] Automatically remove streaming input blocksTathagata Das2014-04-241-2/+5
| | | | | | | | | | | | | | | The raw input data is stored as blocks in BlockManagers. Earlier they were cleared by cleaner ttl. Now since streaming does not require cleaner TTL to be set, the block would not get cleared. This increases up the Spark's memory usage, which is not even accounted and shown in the Spark storage UI. It may cause the data blocks to spill over to disk, which eventually slows down the receiving of data (persisting to memory become bottlenecked by writing to disk). The solution in this PR is to automatically remove those blocks. The mechanism to keep track of which BlockRDDs (which has presents the raw data blocks as a RDD) can be safely cleared already exists. Just use it to explicitly remove blocks from BlockRDDs.

* [Fix #204] Eliminate delay between binding and log checkingAndrew Or2014-04-221-4/+15
| | | | | | | | | | | | | | | **Bug**: In the existing history server, there is a `spark.history.updateInterval` seconds delay before application logs show up on the UI. **Cause**: This is because the following events happen in this order: (1) The background thread that checks for logs starts, but realizes the server has not yet bound and so waits for N seconds, (2) server binds, (3) N seconds later the background thread finds that the server has finally bound to a port, and so finally checks for application logs. **Fix**: This PR forces the log checking thread to start immediately after binding. It also documents two relevant environment variables that are currently missing.

* [SPARK-1439, SPARK-1440] Generate unified Scaladoc across projects and JavadocsMatei Zaharia2014-04-2120-269/+207
| | | | | | | | | | | | | | | | | | | | | | I used the sbt-unidoc plugin (https://github.com/sbt/sbt-unidoc) to create a unified Scaladoc of our public packages, and generate Javadocs as well. One limitation is that I haven't found an easy way to exclude packages in the Javadoc; there is a SBT task that identifies Java sources to run javadoc on, but it's been very difficult to modify it from outside to change what is set in the unidoc package. Some SBT-savvy people should help with this. The Javadoc site also lacks package-level descriptions and things like that, so we may want to look into that. We may decide not to post these right now if it's too limited compared to the Scala one.

* Clean up and simplify Spark configurationPatrick Wendell2014-04-215-186/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Over time as we've added more deployment modes, this have gotten a bit unwieldy with user-facing configuration options in Spark. Going forward we'll advise all users to run `spark-submit` to launch applications. This is a WIP patch but it makes the following improvements: 1. Improved `spark-env.sh.template` which was missing a lot of things users now set in that file. 2. Removes the shipping of SPARK_CLASSPATH, SPARK_JAVA_OPTS, and SPARK_LIBRARY_PATH to the executors on the cluster. This was an ugly hack. Instead it introduces config variables spark.executor.extraJavaOpts, spark.executor.extraLibraryPath, and spark.executor.extraClassPath. 3. Adds ability to set these same variables for the driver using `spark-submit`. 4. Allows you to load system properties from a `spark-defaults.conf` file when running `spark-submit`. This will allow setting both SparkConf options and other system properties utilized by `spark-submit`. 5. Made `SPARK_LOCAL_IP` an environment variable rather than a SparkConf property. This is more consistent with it being set on each node.

* [WIP] SPARK-1430: Support sparse data in Python MLlibMatei Zaharia2014-04-153-25/+58
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This PR adds a SparseVector class in PySpark and updates all the regression, classification and clustering algorithms and models to support sparse data, similar to MLlib. I chose to add this class because SciPy is quite difficult to install in many environments (more so than NumPy), but I plan to add support for SciPy sparse vectors later too, and make the methods work transparently on objects of either type. On the Scala side, we keep Python sparse vectors sparse and pass them to MLlib. We always return dense vectors from our models. Some to-do items left: - [x] Support SciPy's scipy.sparse matrix objects when SciPy is available. We can easily add a function to convert these to our own SparseVector. - [x] MLlib currently uses a vector with one extra column on the left to represent what we call LabeledPoint in Scala. Do we really want this? It may get annoying once you deal with sparse data since you must add/subtract 1 to each feature index when training. We can remove this API in 1.0 and use tuples for labeling. - [x] Explain how to use these in the Python MLlib docs.

Apart from a general review, I need specific input on the following: * I had to move a lot of the existing documentation under the *linear methods* umbrella to accommodate decision trees. I wonder if there is a better way to organize the programming guide given we are so close to the release. * I have not looked closely at pyspark but I am wondering new mllib algorithms are automatically plugged in or do we need to some extra work to call mllib functions from pyspark.

* [SPARK-1276] Add a HistoryServer to render persisted UIAndrew Or2014-04-101-5/+65
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The new feature of event logging, introduced in #42, allows the user to persist the details of his/her Spark application to storage, and later replay these events to reconstruct an after-the-fact SparkUI. Currently, however, a persisted UI can only be rendered through the standalone Master. This greatly limits the use case of this new feature as many people also run Spark on Yarn / Mesos. This PR introduces a new entity called the HistoryServer, which, given a log directory, keeps track of all completed applications independently of a Spark Master. Unlike Master, the HistoryServer needs not be running while the application is still running. It is relatively light-weight in that it only maintains static information of applications and performs no scheduling. To quickly test it out, generate event logs with ```spark.eventLog.enabled=true``` and run ```sbin/start-history-server.sh <log-dir-path>```. Your HistoryServer awaits on port 18080. Comments and feedback are most welcome. --- A few other changes introduced in this PR include refactoring the WebUI interface, which is beginning to have a lot of duplicate code now that we have added more functionality to it. Two new SparkListenerEvents have been introduced (SparkListenerApplicationStart/End) to keep track of application name and start/finish times. This PR also clarifies the semantics of the ReplayListenerBus introduced in #42. A potential TODO in the future (not part of this PR) is to render live applications in addition to just completed applications. This is useful when applications fail, a condition that our current HistoryServer does not handle unless the user manually signals application completion (by creating the APPLICATION_COMPLETION file). Handling live applications becomes significantly more challenging, however, because it is now necessary to render the same SparkUI multiple times. To avoid reading the entire log every time, which is inefficient, we must handle reading the log from where we previously left off, but this becomes fairly complicated because we must deal with the arbitrary behavior of each input stream.

Keep in mind that if we want to open something up in the future we can, but we can never reduce visibility. A few notes here: - In the past we've been inconsistent with the visiblity of the X-RDD classes. This patch marks them private whenever there is an existing function in RDD that can directly creat them (e.g. CoalescedRDD and rdd.coalesce()). One trade-off here is users can't subclass them. - Noted that compression and serialization formats don't have to be wire compatible across versions. - Compression codecs and serialization formats are semi-private as users typically don't instantiate them directly. - Metrics sources are made private - user only interacts with them through Spark's reflection Author: Patrick Wendell <pwendell@gmail.com> Author: Andrew Or <andrewor14@gmail.com> Closes #274 from pwendell/private-apis and squashes the following commits: 44179e4 [Patrick Wendell] Merge remote-tracking branch 'apache-github/master' into private-apis 042c803 [Patrick Wendell] spark.annotations -> spark.annotation bfe7b52 [Patrick Wendell] Adding experimental for approximate counts 8d0c873 [Patrick Wendell] Warning in SparkEnv 99b223a [Patrick Wendell] Cleaning up annotations e849f64 [Patrick Wendell] Merge pull request #2 from andrewor14/annotations 982a473 [Andrew Or] Generalize jQuery matching for non Spark-core API docs a01c076 [Patrick Wendell] Merge pull request #1 from andrewor14/annotations c1bcb41 [Andrew Or] DeveloperAPI -> DeveloperApi 0d48908 [Andrew Or] Comments and new lines (minor) f3954e0 [Andrew Or] Add identifier tags in comments to work around scaladocs bug 99192ef [Andrew Or] Dynamically add badges based on annotations 824011b [Andrew Or] Add support for injecting arbitrary JavaScript to API docs 037755c [Patrick Wendell] Some changes after working with andrew or f7d124f [Patrick Wendell] Small fixes c318b24 [Patrick Wendell] Use CSS styles e4c76b9 [Patrick Wendell] Logging f390b13 [Patrick Wendell] Better visibility for workaround constructors d6b0afd [Patrick Wendell] Small chang to existing constructor 403ba52 [Patrick Wendell] Style fix 870a7ba [Patrick Wendell] Work around for SI-8479 7fb13b2 [Patrick Wendell] Changes to UnionRDD and EmptyRDD 4a9e90c [Patrick Wendell] EXPERIMENTAL API --> EXPERIMENTAL c581dce [Patrick Wendell] Changes after building against Shark. 8452309 [Patrick Wendell] Style fixes 1ed27d2 [Patrick Wendell] Formatting and coloring of badges cd7a465 [Patrick Wendell] Code review feedback 2f706f1 [Patrick Wendell] Don't use floats 542a736 [Patrick Wendell] Small fixes cf23ec6 [Patrick Wendell] Marking GraphX as alpha d86818e [Patrick Wendell] Another naming change 5a76ed6 [Patrick Wendell] More visiblity clean-up 42c1f09 [Patrick Wendell] Using better labels 9d48cbf [Patrick Wendell] Initial pass

| | | | | | | | | | | | | | | | | | | | | | | | | | | This is a fix for [SPARK-1154](https://issues.apache.org/jira/browse/SPARK-1154). The issue is that worker nodes fill up with a huge number of app-* folders after some time. This change adds a periodic cleanup task which asynchronously deletes app directories older than a configurable TTL. Two new configuration parameters have been introduced: spark.worker.cleanup_interval spark.worker.app_data_ttl This change does not include moving the downloads of application jars to a location outside of the work directory. We will address that if we have time, but that potentially involves caching so it will come either as part of this PR or a separate PR.

| | | | | | | | | | | | | | | | | | | | | | | | Previously, we based our decision regarding including datanucleus jars based on the existence of a spark-hive-assembly jar, which was incidentally built whenever "sbt assembly" is run. This means that a typical and previously supported pathway would start using hive jars. This patch has the following features/bug fixes: - Use of SPARK_HIVE (default false) to determine if we should include Hive in the assembly jar. - Analagous feature in Maven with -Phive (previously, there was no support for adding Hive to any of our jars produced by Maven) - assemble-deps fixed since we no longer use a different ASSEMBLY_DIR - avoid adding log message in compute-classpath.sh to the classpath :) Still TODO before mergeable: - We need to download the datanucleus jars outside of sbt. Perhaps we can have spark-class download them if SPARK_HIVE is set similar to how sbt downloads itself. - Spark SQL documentation updates.

| | | | | | | | | | | | | | | | | This is a starting version of the spark-app script for running compiled binaries against Spark. It still needs tests and some polish. The only testing I've done so far has been using it to launch jobs in yarn-standalone mode against a pseudo-distributed cluster. This leaves out the changes required for launching python scripts. I think it might be best to save those for another JIRA/PR (while keeping to the design so that they won't require backwards-incompatible changes).

This component also includes a new public interface, SqlContext, that allows users to execute SQL or structured scala queries against existing RDDs and Parquet files. - Hive Metastore Support (sql/hive) - An extension of SqlContext called HiveContext that allows users to write queries using a subset of HiveQL and access data from a Hive Metastore using Hive SerDes. There are also wrappers that allows users to run queries that include Hive UDFs, UDAFs, and UDTFs. A more complete design of this new component can be found in [the associated JIRA](https://spark-project.atlassian.net/browse/SPARK-1251). [An updated version of the Spark documentation, including API Docs for all three sub-components,](http://people.apache.org/~pwendell/catalyst-docs/sql-programming-guide.html) is also available for review. With this PR comes support for inferring the schema of existing RDDs that contain case classes. Using this information, developers can now express structured queries that are automatically compiled into RDD operations. ```scala // Define the schema using a case class. case class Person(name: String, age: Int) val people: RDD[Person] = sc.textFile("people.txt").map(_.split(",")).map(p => Person(p(0), p(1).toInt)) // The following is the same as 'SELECT name FROM people WHERE age >= 10 && age <= 19' val teenagers = people.where('age >= 10).where('age <= 19).select('name).toRdd ``` RDDs can also be registered as Tables, allowing SQL queries to be written over them. ```scala people.registerAsTable("people") val teenagers = sql("SELECT name FROM people WHERE age >= 10 && age <= 19") ``` The results of queries are themselves RDDs and support standard RDD operations: ```scala teenagers.map(t => "Name: " + t(0)).collect().foreach(println) ``` Finally, with the optional Hive support, users can read and write data located in existing Apache Hive deployments using HiveQL. ```scala sql("CREATE TABLE IF NOT EXISTS src (key INT, value STRING)") sql("LOAD DATA LOCAL INPATH 'src/main/resources/kv1.txt' INTO TABLE src") // Queries are expressed in HiveQL sql("SELECT key, value FROM src").collect().foreach(println) ``` ## Relationship to Shark Unlike Shark, Spark SQL does not act as a drop in replacement for Hive or the HiveServer. Instead this new feature is intended to make it easier for Spark developers to run queries over structured data, using either SQL or the query DSL. After this sub-project graduates from Alpha status it will likely become a new optimizer/backend for the Shark project.

Rows of X correspond to observations and columns correspond to variables. The coefficient matrix is n-by-k. Each column of the coefficients return matrix contains coefficients for one principal component, and the columns are in descending order of component variance. This function centers the data and uses the singular value decomposition (SVD) algorithm. ## Testing Tests included: * All principal components * Only top k principal components * Dense SVD tests * Dense/sparse matrix tests The results are tested against MATLAB's pca: http://www.mathworks.com/help/stats/pca.html ## Documentation Added to mllib-guide.md ## Example Usage Added to examples directory under SparkPCA.scala Author: Reza Zadeh <rizlar@gmail.com> Closes #88 from rezazadeh/sparkpca and squashes the following commits: e298700 [Reza Zadeh] reformat using IDE 3f23271 [Reza Zadeh] documentation and cleanup b025ab2 [Reza Zadeh] documentation e2667d4 [Reza Zadeh] assertMatrixApproximatelyEquals 3787bb4 [Reza Zadeh] stylin c6ecc1f [Reza Zadeh] docs aa2bbcb [Reza Zadeh] rename sparseToTallSkinnyDense 56975b0 [Reza Zadeh] docs 2df9bde [Reza Zadeh] docs update 8fb0015 [Reza Zadeh] rcond documentation dbf7797 [Reza Zadeh] correct argument number a9f1f62 [Reza Zadeh] documentation 4ce6caa [Reza Zadeh] style changes 9a56a02 [Reza Zadeh] use rcond relative to larget svalue 120f796 [Reza Zadeh] housekeeping 156ff78 [Reza Zadeh] string comprehension 2e1cf43 [Reza Zadeh] rename rcond ea223a6 [Reza Zadeh] many style changes f4002d7 [Reza Zadeh] more docs bd53c7a [Reza Zadeh] proper accumulator a8b5ecf [Reza Zadeh] Don't use for loops 0dc7980 [Reza Zadeh] filter zeros in sparse 6115610 [Reza Zadeh] More documentation 36d51e8 [Reza Zadeh] use JBLAS for UVS^-1 computation bc4599f [Reza Zadeh] configurable rcond 86f7515 [Reza Zadeh] compute per parition, use while 09726b3 [Reza Zadeh] more style changes 4195e69 [Reza Zadeh] private, accumulator 17002be [Reza Zadeh] style changes 4ba7471 [Reza Zadeh] style change f4982e6 [Reza Zadeh] Use dense matrix in example 2828d28 [Reza Zadeh] optimizations: normalize once, use inplace ops 72c9fa1 [Reza Zadeh] rename DenseMatrix to TallSkinnyDenseMatrix, lean f807be9 [Reza Zadeh] fix typo 2d7ccde [Reza Zadeh] Array interface for dense svd and pca cd290fa [Reza Zadeh] provide RDD[Array[Double]] support 398d123 [Reza Zadeh] style change 55abbfa [Reza Zadeh] docs fix ef29644 [Reza Zadeh] bad chnage undo 472566e [Reza Zadeh] all files from old pr 555168f [Reza Zadeh] initial files
* [SPARK-1132] Persisting Web UI through refactoring the SparkListener interfaceAndrew Or2014-03-191-1/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The fleeting nature of the Spark Web UI has long been a problem reported by many users: The existing Web UI disappears as soon as the associated application terminates. This is because SparkUI is tightly coupled with SparkContext, and cannot be instantiated independently from it. To solve this, some state must be saved to persistent storage while the application is still running. The approach taken by this PR involves persisting the UI state through SparkListenerEvents. This requires a major refactor of the SparkListener interface because existing events (1) maintain deep references, making de/serialization is difficult, and (2) do not encode all the information displayed on the UI. In this design, each existing listener for the UI (e.g. ExecutorsListener) maintains state that can be fully constructed from SparkListenerEvents. This state is then supplied to the parent UI (e.g. ExecutorsUI), which renders the associated page(s) on demand. This PR introduces two important classes: the **EventLoggingListener**, and the **ReplayListenerBus**. In a live application, SparkUI registers an EventLoggingListener with the SparkContext in addition to the existing listeners. Over the course of the application, this listener serializes and logs all events to persisted storage. Then, after the application has finished, the SparkUI can be revived by replaying all the logged events to the existing UI listeners through the ReplayListenerBus. This feature is currently integrated with the Master Web UI, which optionally rebuilds a SparkUI from event logs as soon as the corresponding application finishes. More details can be found in the commit messages, comments within the code, and the [design doc](https://spark-project.atlassian.net/secure/attachment/12900/PersistingSparkWebUI.pdf). Comments and feedback are most welcome.
