* [SPARK-19348][PYTHON] PySpark keyword_only decorator is not thread-safeBryan Cutler2017-03-031-4/+6
| | | | | | | | | | | | | | ## What changes were proposed in this pull request? The `keyword_only` decorator in PySpark is not thread-safe. It writes kwargs to a static class variable in the decorator, which is then retrieved later in the class method as `_input_kwargs`. If multiple threads are constructing the same class with different kwargs, it becomes a race condition to read from the static class variable before it's overwritten. See [SPARK-19348](https://issues.apache.org/jira/browse/SPARK-19348) for reproduction code. This change will write the kwargs to a member variable so that multiple threads can operate on separate instances without the race condition. It does not protect against multiple threads operating on a single instance, but that is better left to the user to synchronize. ## How was this patch tested? Added new unit tests for using the keyword_only decorator and a regression test that verifies `_input_kwargs` can be overwritten from different class instances. Author: Bryan Cutler <cutlerb@gmail.com> Closes #16782 from BryanCutler/pyspark-keyword_only-threadsafe-SPARK-19348.
* [SPARK-18576][PYTHON] Add basic TaskContext information to PySparkHolden Karau2016-12-201-1/+4
| | | | | | | | | | | | | | ## What changes were proposed in this pull request? Adds basic TaskContext information to PySpark. ## How was this patch tested? New unit tests to `tests.py` & existing unit tests. Author: Holden Karau <holden@us.ibm.com> Closes #16211 from holdenk/SPARK-18576-pyspark-taskcontext.
* [SPARK-1267][SPARK-18129] Allow PySpark to be pip installedHolden Karau2016-11-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This PR aims to provide a pip installable PySpark package. This does a bunch of work to copy the jars over and package them with the Python code (to prevent challenges from trying to use different versions of the Python code with different versions of the JAR). It does not currently publish to PyPI but that is the natural follow up (SPARK-18129). Done: - pip installable on conda [manual tested] - setup.py installed on a non-pip managed system (RHEL) with YARN [manual tested] - Automated testing of this (virtualenv) - packaging and signing with release-build* Possible follow up work: - release-build update to publish to PyPI (SPARK-18128) - figure out who owns the pyspark package name on prod PyPI (is it someone with in the project or should we ask PyPI or should we choose a different name to publish with like ApachePySpark?) - Windows support and or testing ( SPARK-18136 ) - investigate details of wheel caching and see if we can avoid cleaning the wheel cache during our test - consider how we want to number our dev/snapshot versions Explicitly out of scope: - Using pip installed PySpark to start a standalone cluster - Using pip installed PySpark for non-Python Spark programs *I've done some work to test release-build locally but as a non-committer I've just done local testing. ## How was this patch tested? Automated testing with virtualenv, manual testing with conda, a system wide install, and YARN integration. release-build changes tested locally as a non-committer (no testing of upload artifacts to Apache staging websites) Author: Holden Karau <holden@us.ibm.com> Author: Juliet Hougland <juliet@cloudera.com> Author: Juliet Hougland <not@myemail.com> Closes #15659 from holdenk/SPARK-1267-pip-install-pyspark.
* [SPARK-14555] First cut of Python API for Structured StreamingBurak Yavuz2016-04-201-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ## What changes were proposed in this pull request? This patch provides a first cut of python APIs for structured streaming. This PR provides the new classes: - ContinuousQuery - Trigger - ProcessingTime in pyspark under `pyspark.sql.streaming`. In addition, it contains the new methods added under: - `DataFrameWriter` a) `startStream` b) `trigger` c) `queryName` - `DataFrameReader` a) `stream` - `DataFrame` a) `isStreaming` This PR doesn't contain all methods exposed for `ContinuousQuery`, for example: - `exception` - `sourceStatuses` - `sinkStatus` They may be added in a follow up. This PR also contains some very minor doc fixes in the Scala side. ## How was this patch tested? Python doc tests TODO: - [ ] verify Python docs look good Author: Burak Yavuz <brkyvz@gmail.com> Author: Burak Yavuz <burak@databricks.com> Closes #12320 from brkyvz/stream-python.
* [SPARK-10380][SQL] Fix confusing documentation examples for ↵Reynold Xin2016-03-141-0/+20
| | | | | | | | | | | | | | | | astype/drop_duplicates. ## What changes were proposed in this pull request? We have seen users getting confused by the documentation for astype and drop_duplicates, because the examples in them do not use these functions (but do uses their aliases). This patch simply removes all examples for these functions, and say that they are aliases. ## How was this patch tested? Existing PySpark unit tests. Closes #11543.
