* SPARK-1518: FileLogger: Fix compile against Hadoop trunkColin McCabe2014-06-041-4/+12
| | | | | | | | | | | | | In Hadoop trunk (currently Hadoop 3.0.0), the deprecated FSDataOutputStream#sync() method has been removed. Instead, we should call FSDataOutputStream#hflush, which does the same thing as the deprecated method used to do.

* SPARK-1973. Add randomSplit to JavaRDD (with tests, and tidy Java tests)Sean Owen2014-06-042-90/+125
| | | | | | | | | | | | | | | | | | | | | I'd like to use randomSplit through the Java API, and would like to add a convenience wrapper for this method to JavaRDD. This is fairly trivial. (In fact, is the intent that JavaRDD not wrap every RDD method? and that sometimes users should just use JavaRDD.wrapRDD()?) Along the way, I added tests for it, and also touched up the Java API test style and behavior. This is maybe the more useful part of this small change.

* [SPARK-1991] Support custom storage levels for vertices and edgesAnkur Dave2014-06-031-0/+21
| | | | | | | | | | | | | | | | | | | | | This PR adds support for specifying custom storage levels for the vertices and edges of a graph. This enables GraphX to handle graphs larger than memory size by specifying MEMORY_AND_DISK and then repartitioning the graph to use many small partitions, each of which does fit in memory. Spark will then automatically load partitions from disk as needed. The user specifies the desired vertex and edge storage levels when building the graph by passing them to the graph constructor. These are then stored in the `targetStorageLevel` attribute of the VertexRDD and EdgeRDD respectively. Whenever GraphX needs to cache a VertexRDD or EdgeRDD (because it plans to use it more than once, for example), it uses the specified target storage level. Also, when the user calls `Graph#cache()`, the vertices and edges are persisted using their target storage levels. In order to facilitate propagating the target storage levels across VertexRDD and EdgeRDD operations, we remove raw calls to the constructors and instead introduce the `withPartitionsRDD` and `withTargetStorageLevel` methods. I tested this change by running PageRank and triangle count on a severely memory-constrained cluster (1 executor with 300 MB of memory, and a 1 GB graph). Before this PR, these algorithms used to fail with OutOfMemoryErrors. With this PR, and using the DISK_ONLY storage level, they succeed.

* [SPARK-1912] fix compress memory issue during reduceWenchen Fan(Cloud)2014-06-031-2/+20
| | | | | | | | | | | | | | | | When we need to read a compressed block, we will first create a compress stream instance(LZF or Snappy) and use it to wrap that block. Let's say a reducer task need to read 1000 local shuffle blocks, it will first prepare to read that 1000 blocks, which means create 1000 compression stream instance to wrap them. But the initialization of compression instance will allocate some memory and when we have many compression instance at the same time, it is a problem. Actually reducer reads the shuffle blocks one by one, so we can do the compression instance initialization lazily.

* SPARK-1839: PySpark RDD#take() shouldn't always read from driverAaron Davidson2014-05-311-0/+20
| | | | | | | | | | This patch simply ports over the Scala implementation of RDD#take(), which reads the first partition at the driver, then decides how many more partitions it needs to read and will possibly start a real job if it's more than 1.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If I run the following on a YARN cluster ``` bin/spark-submit sheep.py --master yarn-client ``` it fails because of a mismatch in paths: `spark-submit` thinks that `sheep.py` resides on HDFS, and balks when it can't find the file there. A natural workaround is to add the `file:` prefix to the file: ``` bin/spark-submit file:/path/to/sheep.py --master yarn-client ``` However, this also fails. This time it is because python does not understand URI schemes. This PR fixes this by automatically resolving all paths passed as command line argument to `spark-submit` properly. This has the added benefit of keeping file and jar paths consistent across different cluster modes. For python, we strip the URI scheme before we actually try to run it. Much of the code is originally written by @mengxr. Tested on YARN cluster. More tests pending.

* [SPARK-1808] Route bin/pyspark through Spark submitAndrew Or2014-05-164-18/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | **Problem.** For `bin/pyspark`, there is currently no other way to specify Spark configuration properties other than through `SPARK_JAVA_OPTS` in `conf/spark-env.sh`. However, this mechanism is supposedly deprecated. Instead, it needs to pick up configurations explicitly specified in `conf/spark-defaults.conf`. **Solution.** Have `bin/pyspark` invoke `bin/spark-submit`, like all of its counterparts in Scala land (i.e. `bin/spark-shell`, `bin/run-example`). This has the additional benefit of making the invocation of all the user facing Spark scripts consistent. **Details.** `bin/pyspark` inherently handles two cases: (1) running python applications and (2) running the python shell. For (1), Spark submit already handles running python applications. For cases in which `bin/pyspark` is given a python file, we can simply call pass the file directly to Spark submit and let it handle the rest. For case (2), `bin/pyspark` starts a python process as before, which launches the JVM as a sub-process. The existing code already provides a code path to do this. All we needed to change is to use `bin/spark-submit` instead of `spark-class` to launch the JVM. This requires modifications to Spark submit to handle the pyspark shell as a special case. This has been tested locally (OSX and Windows 7), on a standalone cluster, and on a YARN cluster. Running IPython also works as before, except now it takes in Spark submit arguments too.

* [SPARK-1620] Handle uncaught exceptions in function run by Akka schedulerMark Hamstra2014-05-145-18/+36
| | | | | | | | | | | | | | | | If the intended behavior was that uncaught exceptions thrown in functions being run by the Akka scheduler would end up being handled by the default uncaught exception handler set in Executor, and if that behavior is, in fact, correct, then this is a way to accomplish that. I'm not certain, though, that we shouldn't be doing something different to handle uncaught exceptions from some of these scheduled functions. In any event, this PR covers all of the cases I comment on in [SPARK-1620](https://issues.apache.org/jira/browse/SPARK-1620).

* [SPARK-1769] Executor loss causes NPE race conditionAndrew Or2014-05-145-26/+35
| | | | | | | | | | | | | | | | | | This PR replaces the Schedulable data structures in Pool.scala with thread-safe ones from java. Note that Scala's `with SynchronizedBuffer` trait is soon to be deprecated in 2.11 because it is ["inherently unreliable"](http://www.scala-lang.org/api/2.11.0/index.html#scala.collection.mutable.SynchronizedBuffer). We should slowly drift away from `SynchronizedBuffer` in other places too. Note that this PR introduces an API-breaking change; `sc.getAllPools` now returns an Array rather than an ArrayBuffer. This is because we want this method to return an immutable copy rather than one may potentially confuse the user if they try to modify the copy, which takes no effect on the original data structure.
