[jira] [Created] (SPARK-10710) Remove ability to set spark.shuffle.spill=false

Josh Rosen created SPARK-10710:
----------------------------------

             Summary: Remove ability to set spark.shuffle.spill=false
                 Key: SPARK-10710
                 URL: https://issues.apache.org/jira/browse/SPARK-10710
             Project: Spark
          Issue Type: Sub-task
          Components: Shuffle
            Reporter: Josh Rosen


The {{spark.shuffle.spill=false}} configuration doesn't make much sense nowadays: I think that this configuration was only added as an escape-hatch to guard against bugs when spilling was first added.

In order to reduce complexity, I think that we should remove the ability to disable spilling. Note that the {{tungsten-shuffle}} manager already does not respect this setting, so removing this configuration is a blocker to being able to unify the two sort-shuffle implementations.
