Resolution: Duplicate
> Follow-up on ResourceManager quit due to ApplicationStateData exceeding
> znode limit
> ------------------------------------------------------------------------------------
>
> Key: HADOOP-19316
> URL: https://issues.apache.org/jira/browse/HADOOP-19316
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 3.3.6
> Reporter: Haitian
> Priority: Major
>
> In 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.
