[jira] [Updated] (SPARK-3460) Discard executors

     [ https://issues.apache.org/jira/browse/SPARK-3460?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.
