Sandy Ryza updated SPARK-3460:
------------------------------
Summary: Discard executors (was: Graceful decommission of idle YARN
sessions)
> Discard executors
> -----------------
>
> Key: SPARK-3460
> URL: https://issues.apache.org/jira/browse/SPARK-3460
> Project: Spark
> Issue Type: Sub-task
> Components: YARN
> Reporter: Patrick Wendell
> Assignee: Andrew Or
>
> This is a simpler case of the more general ideas discussed in SPARK-3174. If
> we have a YARN session that is no longer submitting tasks and has no in-scope
> shuffle data or cached blocks, then we should scale down the cluster and give
> up containers.
> This general behavior could be enabled/disabled with a config setting.
