-----------------------------------

             Summary: RMRegistryOperationService don't have limit on AsyncPurge threads
                 Key: YARN-8291
                 URL: https://issues.apache.org/jira/browse/YARN-8291
             Project: Hadoop YARN
          Issue Type: Bug
          Components: yarn
    Affects Versions: 2.7.3
            Reporter: Prabhu Joseph


When there are more than 10000+ containers finished - RMRegistryOperationService will create 10000+ threads for performing AsyncPurge which can slowdown the ResourceManager process. There should be a limit on the number of threads.
