Summary: 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
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.
