Jian He commented on YARN-2268: ------------------------------- I think the lock file solution only suits zk-store, not for other state-store implementations. The current approach of polling web service should be more general. > Disallow formatting the RMStateStore when there is an RM running > ---------------------------------------------------------------- > > Key: YARN-2268 > URL: https://issues.apache.org/jira/browse/YARN-2268 > Project: Hadoop YARN > Issue Type: Improvement > Components: resourcemanager > Affects Versions: 2.6.0 > Reporter: Karthik Kambatla > Assignee: Rohith > Attachments: 0001-YARN-2268.patch > > > YARN-2131 adds a way to format the RMStateStore. However, it can be a problem > if we format the store while an RM is actively using it. It would be nice to > fail the format if there is an RM running and using this store. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
