* [SPARK-12380] [PYSPARK] use SQLContext.getOrCreate in mllibDavies Liu2015-12-161-5/+5
| | | | | | | | MLlib should use SQLContext.getOrCreate() instead of creating new SQLContext. Author: Davies Liu <davies@databricks.com> Closes #10338 from davies/create_context.
* [SPARK-10272][PYSPARK][MLLIB] Added @since tags to pyspark.mllib.evaluationnoelsmith2015-10-201-0/+41
| | | | | | | | | | | | Duplicated the since decorator from pyspark.sql into pyspark (also tweaked to handle functions without docstrings). Added since to public methods + "versionadded::" to classes (derived from the git file history in pyspark). Note - I added also the tags to MultilabelMetrics even though it isn't declared as public in the __all__ statement... if that's incorrect - I'll remove. Author: noelsmith <mail@noelsmith.com> Closes #8628 from noel-smith/SPARK-10272-since-mllib-evalutation.
* [DOC] [PYSPARK] [MLLIB] Added newlines to docstrings to fix parameter formattingnoelsmith2015-09-211-1/+1
| | | | | | | | | | | | | | Added newlines before `:param ...:` and `:return:` markup. Without these, parameter lists aren't formatted correctly in the API docs. I.e: ![screen shot 2015-09-21 at 21 49 26](https://cloud.githubusercontent.com/assets/11915197/10004686/de3c41d4-60aa-11e5-9c50-a46dcb51243f.png) .. looks like this once newline is added: ![screen shot 2015-09-21 at 21 50 14](https://cloud.githubusercontent.com/assets/11915197/10004706/f86bfb08-60aa-11e5-8524-ae4436713502.png) Author: noelsmith <mail@noelsmith.com> Closes #8851 from noel-smith/docstring-missing-newline-fix.

* [SPARK-6090][MLLIB] add a basic BinaryClassificationMetrics to PySpark/MLlibXiangrui Meng2015-03-051-0/+83
A simple wrapper around the Scala implementation. `DataFrame` is used for serialization/deserialization. Methods that return `RDD`s are not supported in this PR. davies If we recognize Scala's `Product`s in Py4J, we can easily add wrappers for Scala methods that returns `RDD[(Double, Double)]`. Is it easy to register serializer for `Product` in PySpark?
