Bibin A Chundatt created YARN-6531:
--------------------------------------

             Summary: Sanity check appStateData size before saving to Zookeeper
                 Key: YARN-6531
                 URL: https://issues.apache.org/jira/browse/YARN-6531
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Bibin A Chundatt
            Assignee: Bibin A Chundatt
            Priority: Critical


Application with large size Application submission context could cause store to Zookeeper
failure due to znode size limit. Zookeeper znode limit exception thrown {{org.apache.zookeeper.KeeperException$ConnectionLossException}}.
ZkStateStore will retry for configured times and will throw ConnectionLossException after
configured limit.
Which could cause Resource manager to switch from active To StandBy and other application
submitted not getting save to ZK.
Solution {{ApplicationStateData}} size to be validated before saving and reject application
so that ResourceManager is not impacted.
