* [SPARK-13843][STREAMING] Remove streaming-flume, streaming-mqtt, ↵Shixiong Zhu2016-03-143-473/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | streaming-zeromq, streaming-akka, streaming-twitter to Spark packages ## What changes were proposed in this pull request? Currently there are a few sub-projects, each for integrating with different external sources for Streaming. Now that we have better ability to include external libraries (spark packages) and with Spark 2.0 coming up, we can move the following projects out of Spark to https://github.com/spark-packages - streaming-flume - streaming-akka - streaming-mqtt - streaming-zeromq - streaming-twitter They are just some ancillary packages and considering the overhead of maintenance, running tests and PR failures, it's better to maintain them out of Spark. In addition, these projects can have their different release cycles and we can release them faster. I have already copied these projects to https://github.com/spark-packages ## How was this patch tested? Jenkins tests Author: Shixiong Zhu <shixiong@databricks.com> Closes #11672 from zsxwing/remove-external-pkg.
* [SPARK-13848][SPARK-5185] Update to Py4J 0.9.2 in order to fix classloading ↵Josh Rosen2016-03-145-49/+22
| | | | | | | | | | | | | | | | issue This patch upgrades Py4J from 0.9.1 to 0.9.2 in order to include a patch which modifies Py4J to use the current thread's ContextClassLoader when performing reflection / class loading. This is necessary in order to fix [SPARK-5185](https://issues.apache.org/jira/browse/SPARK-5185), a longstanding issue affecting the use of `--jars` and `--packages` in PySpark. In order to demonstrate that the fix works, I removed the workarounds which were added as part of [SPARK-6027](https://issues.apache.org/jira/browse/SPARK-6027) / #4779 and other patches. Py4J diff: https://github.com/bartdag/py4j/compare/0.9.1...0.9.2 /cc zsxwing tdas davies brkyvz Author: Josh Rosen <joshrosen@databricks.com> Closes #11687 from JoshRosen/py4j-0.9.2.

| | | | | | | | | | | | streaming This patch de-duplicates code in PySpark streaming which loads the `Python*Helper` classes. I also changed a few `raise e` statements to simply `raise` in order to preserve the full exception stacktrace when re-throwing.

* [SPARK-7997][CORE] Add rpcEnv.awaitTermination() back to SparkEnvShixiong Zhu2016-02-021-2/+2
| | | | | | | | | | | | `rpcEnv.awaitTermination()` was not added in #10854 because some Streaming Python tests hung forever. This patch fixed the hung issue and added rpcEnv.awaitTermination() back to SparkEnv. Previously, Streaming Kafka Python tests shutdowns the zookeeper server before stopping StreamingContext. Then when stopping StreamingContext, KafkaReceiver may be hung due to https://issues.apache.org/jira/browse/KAFKA-601, hence, some thread of RpcEnv's Dispatcher cannot exit and rpcEnv.awaitTermination is hung.The patch just changed the shutdown order to fix it.

* [SPARK-12511] [PYSPARK] [STREAMING] Make sure ↵Shixiong Zhu2016-01-052-10/+26
| | | | | | | | | | | | PythonDStream.registerSerializer is called only once There is an issue that Py4J's PythonProxyHandler.finalize blocks forever. (https://github.com/bartdag/py4j/pull/184) Py4j will create a PythonProxyHandler in Java for "transformer_serializer" when calling "registerSerializer". If we call "registerSerializer" twice, the second PythonProxyHandler will override the first one, then the first one will be GCed and trigger "PythonProxyHandler.finalize". To avoid that, we should not call"registerSerializer" more than once, so that "PythonProxyHandler" in Java side won't be GCed.

* [SPARK-12091] [PYSPARK] Deprecate the JAVA-specific deserialized storage levelsgatorsmile2015-12-185-7/+7
| | | | | | | | | | | | | | The current default storage level of Python persist API is MEMORY_ONLY_SER. This is different from the default level MEMORY_ONLY in the official document and RDD APIs. davies Is this inconsistency intentional? Thanks! Updates: Since the data is always serialized on the Python side, the storage levels of JAVA-specific deserialization are not removed, such as MEMORY_ONLY. Updates: Based on the reviewers' feedback. In Python, stored objects will always be serialized with the [Pickle](https://docs.python.org/2/library/pickle.html) library, so it does not matter whether you choose a serialized level. The available storage levels in Python include `MEMORY_ONLY`, `MEMORY_ONLY_2`, `MEMORY_AND_DISK`, `MEMORY_AND_DISK_2`, `DISK_ONLY`, `DISK_ONLY_2` and `OFF_HEAP`.

* [SPARK-11904][PYSPARK] reduceByKeyAndWindow does not require checkpointing ↵David Tolpin2015-12-161-22/+23
| | | | | | | | | | | | | | | | when invFunc is None when invFunc is None, `reduceByKeyAndWindow(func, None, winsize, slidesize)` is equivalent to reduceByKey(func).window(winsize, slidesize).reduceByKey(winsize, slidesize) and no checkpoint is necessary. The corresponding Scala code does exactly that, but Python code always creates a windowed stream with obligatory checkpointing. The patch fixes this. I do not know how to unit-test this.

* [SPARK-12058][STREAMING][KINESIS][TESTS] fix Kinesis python testsBurak Yavuz2015-12-041-1/+0
| | | | | | | | | | | | Python tests require access to the `KinesisTestUtils` file. When this file exists under src/test, python can't access it, since it is not available in the assembly jar. However, if we move KinesisTestUtils to src/main, we need to add the KinesisProducerLibrary as a dependency. In order to avoid this, I moved KinesisTestUtils to src/main, and extended it with ExtendedKinesisTestUtils which is under src/test that adds support for the KPL. cc zsxwing tdas Author: Burak Yavuz <brkyvz@gmail.com> Closes #10050 from brkyvz/kinesis-py.

| | | | | | | | | | | | | reduceByKeyAndWindow invFunc is optional and can be None. Instead of invFunc (the parameter) invReduceFunc (a local function) was checked for trueness (that is, not None, in this context). A local function is never None, thus the case of invFunc=None (a common one when inverse reduction is not defined) was treated incorrectly, resulting in loss of data. In addition, the docstring used wrong parameter names, also fixed. Author: David Tolpin <david.tolpin@gmail.com> Closes #9775 from dtolpin/master.

The solution is to do the following: 1. Use the same code path as Java to check whether a valid checkpoint exists 2. Create a new Python SparkContext only if there no active one. There is not test for the path as its hard to test with distributed filesystem paths in a local unit test.

* [SPARK-8389] [STREAMING] [PYSPARK] Expose KafkaRDDs offsetRange in Pythonjerryshao2015-07-093-11/+183
| | | | | | | | | | | | | | | | | | | | | | This PR propose a simple way to expose OffsetRange in Python code, also the usage of offsetRanges is similar to Scala/Java way, here in Python we could get OffsetRange like: ``` dstream.foreachRDD(lambda r: KafkaUtils.offsetRanges(r)) ``` Reason I didn't follow the way what SPARK-8389 suggested is that: Python Kafka API has one more step to decode the message compared to Scala/Java, Which makes Python API return a transformed RDD/DStream, not directly wrapped so-called JavaKafkaRDD, so it is hard to backtrack to the original RDD to get the offsetRange.

This allows the pull request builder to skip Python tests suites that were not affected by the pull request's changes. For example, we can now skip the PySpark Streaming test cases when only SQL files are changed. - `python/run-tests` now supports command-line flags to make it easier to run individual test suites (this addresses SPARK-5482): ``` Usage: run-tests [options] Options: -h, --help show this help message and exit --python-executables=PYTHON_EXECUTABLES A comma-separated list of Python executables to test against (default: python2.6,python3.4,pypy) --modules=MODULES A comma-separated list of Python modules to test (default: pyspark-core,pyspark-ml,pyspark-mllib ,pyspark-sql,pyspark-streaming) ``` - `dev/run-tests` has been split into multiple files: the module definitions and test utility functions are now stored inside of a `dev/sparktestsupport` Python module, allowing them to be re-used from the Python test runner script.

* [SPARK-8652] [PYSPARK] Check return value for all uses of doctest.testmod()Josh Rosen2015-06-261-1/+3
| | | | | | | | | | | | | | | | This patch addresses a critical issue in the PySpark tests: Several of our Python modules' `__main__` methods call `doctest.testmod()` in order to run doctests but forget to check and handle its return value. As a result, some PySpark test failures can go unnoticed because they will not fail the build. Fortunately, there was only one test failure which was masked by this bug: a `pyspark.profiler` doctest was failing due to changes in RDD pipelining.
