Subject [GitHub] spark pull request: SPARK-1630: Make PythonRDD handle NULL element...

    I see your point. I don't have a Python-only use-case that can trigger the NPE.
    
    My custom RDD implementation had a corner-case in which RDD's compute() method returned
a "null" in the iterator stream. I have fixed my custom RDD implementation to not do that,
so I don't run into this NPE anymore. However, should anyone else out there ever implement
a custom RDD of similar nature (has nulls for some elements in a partition's iterator stream)
and tries accessing such an RDD from PySpark, he/she would run into the NPE, so I thought
it would be nicer if we handled nulls in the stream gracefully.
