Robert Kanter created YARN-2241: ----------------------------------- Summary: Show nicer messages when ZNodes already exist in ZKRMStateStore on startup Key: YARN-2241 URL: https://issues.apache.org/jira/browse/YARN-2241 Project: Hadoop YARN Issue Type: Bug Affects Versions: 2.5.0 Reporter: Robert Kanter Assignee: Robert Kanter Priority: Minor
When using the RMZKStateStore, if you restart the RM, you get a bunch of stack traces with messages like {{org.apache.zookeeper.KeeperException$NodeExistsException: KeeperErrorCode = NodeExists for /rmstore}}. This is expected as these nodes already exist from before. We should catch these and print nicer messages. -- This message was sent by Atlassian JIRA (v6.2#6252)
