Priority: Minor (was: Major)
Component/s: Mesos
> Support cleaning up shuffle files for drivers launched with Mesos
> -----------------------------------------------------------------
>
> Key: SPARK-8873
> URL: https://issues.apache.org/jira/browse/SPARK-8873
> Project: Spark
> Issue Type: Improvement
> Components: Mesos
> Reporter: Timothy Chen
> Priority: Minor
> Labels: mesos
>
> With dynamic allocation enabled with Mesos, drivers can launch with shuffle data cached in the external shuffle service.
> However, there is no reliable way to let the shuffle service clean up the shuffle data when the driver exits, since it may crash before it notifies the shuffle service and shuffle data will be cached forever.
> We need to implement a reliable way to detect driver termination and clean up shuffle data accordingly.
