[SPARK-2601] [PySpark] Fix Py4J error when transforming pickleFiles
Similar to SPARK-1034, the problem was that Py4J didnât cope well with
the fake ClassTags used in the Java API. It doesnât look like thereâs any
reason why PythonRDD needs to take a ClassTag, since it just ignores the type
of the previous RDD, so I removed the type parameter and we no longer pass
ClassTags from Python.
