[jira] [Created] (SPARK-15971) GroupedData's member incorrectly named

Vladimir Feinberg created SPARK-15971:
-----------------------------------------

             Summary: GroupedData's member incorrectly named
                 Key: SPARK-15971
                 URL: https://issues.apache.org/jira/browse/SPARK-15971
             Project: Spark
          Issue Type: Improvement
          Components: PySpark
    Affects Versions: 2.0.0, 2.1.0
            Reporter: Vladimir Feinberg
            Priority: Trivial


The [[pyspark.sql.GroupedData]] object calls the Java object it wraps around as the member variable [[self._jdf]], which is exactly the same as [[pyspark.sql.DataFrame]], when referring its object.

The acronym is incorrect, standing for "Java DataFrame" instead of what should be "Java GroupedData". As such, the name should be changed to [[self._jgd]] - in fact, in the [[DataFrame.groupBy]] implementation, the java object is referred to as exactly [[jgd]]
