------------------------------------
> Graceful decommission of executors
> ----------------------------------
>
> Key: SPARK-3464
> URL: https://issues.apache.org/jira/browse/SPARK-3464
> Project: Spark
> Issue Type: Bug
> Components: YARN
> Affects Versions: 1.1.0
> Reporter: Sandy Ryza
> Assignee: Andrew Or
>
> In most cases, even when an application is utilizing only a small fraction of its available
resources, executors will still have tasks running or blocks cached. It would be useful to
have a mechanism for waiting for running tasks on an executor to finish and migrating its
cached blocks elsewhere before discarding it.
