Vladimir Feinberg updated SPARK-15971:
--------------------------------------
Description:
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}}
