> 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}}
