-------------------------------
Issue Type: Sub-task (was: Task)
Parent: YARN-7402
> [GPG] add Yarn Registry cleanup in ApplicationCleaner
> -----------------------------------------------------
>
> Key: YARN-8862
> URL: https://issues.apache.org/jira/browse/YARN-8862
> Project: Hadoop YARN
> Issue Type: Sub-task
> Reporter: Botong Huang
> Assignee: Botong Huang
> Priority: Major
>
> In Yarn Federation, we use Yarn Registry to use the AMToken for UAMs in
> secondary sub-clusters. Because of potential more app attempts later,
> AMRMProxy cannot kill the UAM and delete the tokens when one local attempt
> finishes. So similar to the StateStore application table, we need
> ApplicationCleaner in GPG to cleanup the finished app entries in Yarn
> Registry.
