| |\ | | | | | | | | | | | | | | | | | | | | | Moved DStream and PairDSream to org.apache.spark.streaming.dstream Similar to the package location of `org.apache.spark.rdd.RDD`, `DStream` has been moved from `org.apache.spark.streaming.DStream` to `org.apache.spark.streaming.dstream.DStream`. I know that the package name is a little long, but I think its better to keep it consistent with Spark's structure. Also fixed persistence of windowed DStream. The RDDs generated generated by windowed DStream are essentially unions of underlying RDDs, and persistent these union RDDs would store numerous copies of the underlying data. Instead setting the persistence level on the windowed DStream is made to set the persistence level of the underlying DStream.

| |\ \ \ | | |_|/ | |/| | | | | | | | | | | | | | Disable shuffle file consolidation by default After running various performance tests for the 0.9 release, this still seems to have performance issues even on XFS. So let's keep this off-by-default for 0.9 and users can experiment with it depending on their disk configurations.

| |/ | | | | | | | | | | `foreachRDD` makes it clear that the granularity of this operator is per-RDD. As it stands, `foreach` is inconsistent with with `map`, `filter`, and the other DStream operators which get pushed down to individual records within each RDD.

| |\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | External Sorting for Aggregator and CoGroupedRDDs (Revisited) (This pull request is re-opened from https://github.com/apache/incubator-spark/pull/303, which was closed because Jenkins / github was misbehaving) The target issue for this patch is the out-of-memory exceptions triggered by aggregate operations such as reduce, groupBy, join, and cogroup. The existing AppendOnlyMap used by these operations resides purely in memory, and grows with the size of the input data until the amount of allocated memory is exceeded. Under large workloads, this problem is aggravated by the fact that OOM frequently occurs only after a very long (> 1 hour) map phase, in which case the entire job must be restarted. The solution is to spill the contents of this map to disk once a certain memory threshold is exceeded. This functionality is provided by ExternalAppendOnlyMap, which additionally sorts this buffer before writing it out to disk, and later merges these buffers back in sorted order. Under normal circumstances in which OOM is not triggered, ExternalAppendOnlyMap is simply a wrapper around AppendOnlyMap and incurs little overhead. Only when the memory usage is expected to exceed the given threshold does ExternalAppendOnlyMap spill to disk.

| | | | | | | | | | | | | | | | | | | | | | | | Aside from trivial formatting changes, use nulls instead of Options for DiskMapIterator, and add documentation for spark.shuffle.externalSorting and spark.shuffle.memoryFraction. Also, set spark.shuffle.memoryFraction to 0.3, and spark.storage.memoryFraction = 0.6.

This patch removes compatibility for IPython < 1.0 but fixes the launch script and makes it much simpler. I tested this using the three commands in the PySpark documentation page: 1. IPYTHON=1 ./pyspark 2. IPYTHON_OPTS="notebook" ./pyspark 3. IPYTHON_OPTS="notebook --pylab inline" ./pyspark There are two changes: - We rely on PYTHONSTARTUP env var to start PySpark - Removed the quotes around $IPYTHON_OPTS... having quotes gloms them together as a single argument passed to `exec` which seemed to cause ipython to fail (it instead expects them as multiple arguments).

It also supports monitoring and re-launching of driver programs which is useful for long running, recoverable applications such as Spark Streaming jobs. For those jobs, this patch allows a deployment mode which is resilient to the failure of any worker node, failure of a master node (provided a multi-master setup), and even failures of the applicaiton itself, provided they are recoverable on a restart. Driver information, such as the status and logs from a driver, is displayed in the UI There are a few small TODO's here, but the code is generally feature-complete. They are: - Bring tests up to date and add test coverage - Restarting on failure should be optional and maybe off by default. - See if we can re-use akka connections to facilitate clients behind a firewall A sensible place to start for review would be to look at the `DriverClient` class which presents users the ability to launch their driver program. I've also added an example program (`DriverSubmissionTest`) that allows you to test this locally and play around with killing workers, etc. Most of the code is devoted to persisting driver state in the cluster manger, exposing it in the UI, and dealing correctly with various types of failures. Instructions to test locally: - `sbt/sbt assembly/assembly examples/assembly` - start a local version of the standalone cluster manager ``` ./spark-class org.apache.spark.deploy.client.DriverClient \ -j -Dspark.test.property=something \ -e SPARK_TEST_KEY=SOMEVALUE \ launch spark://10.99.1.14:7077 \ ../path-to-examples-assembly-jar \ org.apache.spark.examples.DriverSubmissionTest 1000 some extra options --some-option-here -X 13 ``` - Go in the UI and make sure it started correctly, look at the output etc - Kill workers, the driver program, masters, etc.
