* [SPARK-16950] [PYSPARK] fromOffsets parameter support in ↵Mariusz Strzelecki2016-08-091-9/+3
| | | | | | | | | | | | | | | | | | KafkaUtils.createDirectStream for python3 ## What changes were proposed in this pull request? Ability to use KafkaUtils.createDirectStream with starting offsets in python 3 by using java.lang.Number instead of Long during param mapping in scala helper. This allows py4j to pass Integer or Long to the map and resolves ClassCastException problems. ## How was this patch tested? unit tests jerryshao - could you please look at this PR? Author: Mariusz Strzelecki <mariusz.strzelecki@allegrogroup.com> Closes #14540 from szczeles/kafka_pyspark.

* [SPARK-14936][BUILD][TESTS] FlumePollingStreamSuite is slowXin Ren2016-05-101-1/+1
| | | | | | | | | | | | | | | | | | | | https://issues.apache.org/jira/browse/SPARK-14936 ## What changes were proposed in this pull request? FlumePollingStreamSuite contains two tests which run for a minute each. This seems excessively slow and we should speed it up if possible. In this PR, instead of creating `StreamingContext` directly from `conf`, here an underlying `SparkContext` is created before all and it is used to create each`StreamingContext`. Running time is reduced by avoiding multiple `SparkContext` creations and destroys. ## How was this patch tested? Tested on my local machine running `testOnly *.FlumePollingStreamSuite` Author: Xin Ren <iamshrek@126.com> Closes #12845 from keypointt/SPARK-14936.
* [SPARK-13579][BUILD] Stop building the main Spark assembly.Marcelo Vanzin2016-04-041-3/+3
| | | | | | | | | | | | | | | | | | | | This change modifies the "assembly/" module to just copy needed dependencies to its build directory, and modifies the packaging script to pick those up (and remove duplicate jars packages in the examples module). I also made some minor adjustments to dependencies to remove some test jars from the final packaging, and remove jars that conflict with each other when packaged separately (e.g. servlet api). Also note that this change restores guava in applications' classpaths, even though it's still shaded inside Spark. This is now needed for the Hadoop libraries that are packaged with Spark, which now are not processed by the shade plugin. Author: Marcelo Vanzin <vanzin@cloudera.com> Closes #11796 from vanzin/SPARK-13579.
* [SPARK-14073][STREAMING][TEST-MAVEN] Move flume back to SparkShixiong Zhu2016-03-251-3/+165

* [SPARK-13843][STREAMING] Remove streaming-flume, streaming-mqtt, ↵Shixiong Zhu2016-03-141-263/+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 Rosen2016-03-141-20/+5
| | | | | | | | | | | | | | | | 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.

* [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-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.

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.

| | | | | | | | | | | | | | | | | | checkpoint paths and existing SparkContexts The current code only checks checkpoint files in local filesystem, and always tries to create a new Python SparkContext (even if one already exists). 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. I am going to test it with a distributed file system manually to verify that this patch works.

| | | | | | | | | | | | | | | | | | | | | | 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.

This format is useful for numerical array data, e.g. in scientific computing applications. This PR adds support for the same format in Streaming applications, where it is similarly useful, especially for streaming time series or sensor data. Summary of additions - adding `binaryRecordsStream` to Spark Streaming - exposing `binaryRecordsStream` in the new PySpark Streaming - new unit tests in Scala and Python This required adding an optional Hadoop configuration param to `fileStream` and `FileInputStream`, but was otherwise straightforward. tdas davies Author: freeman <the.freeman.lab@gmail.com> Closes #3803 from freeman-lab/streaming-binary-records and squashes the following commits: b676534 [freeman] Clarify note 5ff1b75 [freeman] Add note to java streaming context eba925c [freeman] Simplify notes c4237b8 [freeman] Add experimental tag 30eba67 [freeman] Add filter and newFilesOnly alongside conf c2cfa6d [freeman] Expose new version of fileStream with conf in java 34d20ef [freeman] Add experimental tag 14bca9a [freeman] Add experimental tag b85bffc [freeman] Formatting 47560f4 [freeman] Space formatting 9a3715a [freeman] Refactor to reflect changes to FileInputSuite 7373f73 [freeman] Add note and defensive assertion for byte length 3ceb684 [freeman] Merge remote-tracking branch 'upstream/master' into streaming-binary-records 317b6d1 [freeman] Make test inline fcb915c [freeman] Formatting becb344 [freeman] Formatting d3e75b2 [freeman] Add tests in python a4324a3 [freeman] Line length 029d49c [freeman] Formatting 1c739aa [freeman] Simpler default arg handling 94d90d0 [freeman] Spelling 2843e9d [freeman] Add params to docstring 8b70fbc [freeman] Reorganization 28bff9b [freeman] Fix missing arg 9398bcb [freeman] Expose optional hadoop configuration 23dd69f [freeman] Tests for binaryRecordsStream 36cb0fd [freeman] Add binaryRecordsStream to scala fe4e803 [freeman] Add binaryRecordStream to Java API ecef0eb [freeman] Add binaryRecordsStream to python 8550c26 [freeman] Expose additional argument combination
