Reynold Xin resolved SPARK-7855.
--------------------------------
Resolution: Fixed
Fix Version/s: 1.5.0
> 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: Improvement
> Components: Shuffle
> Reporter: Josh Rosen
> Assignee: Josh Rosen
> Fix For: 1.5.0
>
>
> 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)
