----------------------------------
Summary: [GPG] add Yarn Registry cleanup in ApplicationCleaner
Key: YARN-8862
URL: https://issues.apache.org/jira/browse/YARN-8862
Project: Hadoop YARN
Issue Type: Task
Reporter: Botong Huang
Assignee: Botong Huang
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.
