[jira] [Created] (SPARK-7855) Move hash-style shuffle code out of ExternalSorter and into own file

Josh Rosen created SPARK-7855:
---------------------------------

             Summary: Move hash-style shuffle code out of ExternalSorter and into own file
                 Key: SPARK-7855
                 URL: https://issues.apache.org/jira/browse/SPARK-7855
             Project: Spark
          Issue Type: Bug
          Components: Shuffle
            Reporter: Josh Rosen
            Assignee: Josh Rosen


ExternalSorter contains a bunch of code for handling the bypassMergeThreshold / hash-style shuffle path.  I think that it would significantly simplify the code to move this functionality out of ExternalSorter and into a separate class which shares a common interface (insertAll / writePartitionedFile()).  This is a stepping-stone towards eventually removing this bypass path (see SPARK-6026)
