--------------------------------------
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.
