----------------------------------------
Is anyone working on this ? If not, I would like to work on this.
> Implement custom bye array serializer for use in PySpark shuffle
> ----------------------------------------------------------------
>
> Key: SPARK-7448
> URL: https://issues.apache.org/jira/browse/SPARK-7448
> Project: Spark
> Issue Type: Improvement
> Components: PySpark, Shuffle
> Reporter: Josh Rosen
> Priority: Minor
>
> PySpark's shuffle typically shuffles Java RDDs that contain byte arrays. We
> should implement a custom Serializer for use in these shuffles. This will
> allow us to take advantage of shuffle optimizations like SPARK-7311 for
> PySpark without requiring users to change the default serializer to
> KryoSerializer (this is useful for JobServer-type applications).
