URL: https://github.com/apache/hadoop/pull/7257

   https://issues.apache.org/jira/browse/YARN-11741
   
   In [YARN-5006](https://issues.apache.org/jira/browse/YARN-5006) the issue 
"ResourceManager quit due to ApplicationStateData exceeding znode limit" has 
been addressed , specifically in the storeApplicationStateInternal() method of 
the ZKRMStateStore class. However, the methods 
updateApplicationStateInternal(), storeApplicationAttemptStateInternal(), and 
updateApplicationAttemptStateInternal() also need to incorporate checks for the 
ZNode size limit in  ZKRMStateStore class. This will help prevent scenarios 
where excessive data written to a single ZNode causes the ResourceManager (RM) 
and ZooKeeper (ZK) services to become unavailable.
