Subject [GitHub] spark pull request: Adding zipPartitions to PySpark
Date Tue, 05 Jan 2016 00:21:45 GMT

    The one socket for PythonRDD is already pretty complicated (considering how propagate
exception and how to re-use it), adding another will make it even complicated (two socket
in different status), so I'd try to avoid that. The new introduced and not-common-used zipPartititon()
should not brings bugs for existing workload. I'd -1 for current approach, cc @JoshRosen .
    
    Another try could be that only open second socket (not re-used) when zipPartition() is
called, this may reduce the risk for existing workload.
