             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.
