[jira] [Created] (SPARK-14768) Remove expectedType arg for PySpark Param

Joseph K. Bradley created SPARK-14768:
-----------------------------------------

             Summary: Remove expectedType arg for PySpark Param
                 Key: SPARK-14768
                 URL: https://issues.apache.org/jira/browse/SPARK-14768
             Project: Spark
          Issue Type: Improvement
          Components: ML, PySpark
            Reporter: Joseph K. Bradley
            Priority: Minor


We could go ahead and removed the expectedType in 2.0. The only reason to keep it is to avoid breaking 3rd party implementations of PipelineStages in Python which happen to be using the expectedType arg.  I doubt there are many such implementations.

Keeping that argument has led to problems with mixing the expectedType and typeConverter args, as in [https://github.com/apache/spark/pull/12480]
