             Summary: Python API parity issues from 2.0 QA
                 Key: SPARK-16486
                 URL: https://issues.apache.org/jira/browse/SPARK-16486
             Project: Spark
          Issue Type: Sub-task
          Components: Documentation, ML, PySpark
            Reporter: Joseph K. Bradley
            Assignee: holdenk
            Priority: Blocker


For new public APIs added to MLlib, we need to check the generated HTML doc and compare the Scala & Python versions.  We need to track:
* Inconsistency: Do class/method/parameter names match?
* Docs: Is the Python doc missing or just a stub?  We want the Python doc to be as complete as the Scala doc.
* API breaking changes: These should be very rare but are occasionally either necessary (intentional) or accidental.  These must be recorded and added in the Migration Guide for this release.
** Note: If the API change is for an Alpha/Experimental/DeveloperApi component, please note that as well.
* Missing classes/methods/parameters: We should create to-do JIRAs for functionality missing from Python, to be added in the next release cycle.  Please use a *separate* JIRA (linked below as "requires") for this list of to-do items.
** *NOTE: These missing features should be added in the next release.  This work is just to generate a list of to-do items for the future.*

UPDATE: This only needs to cover spark.ml since spark.mllib is going into maintenance mode.
