> 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.
