----------------------------------
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.
