> 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: Bug
> Components: resourcemanager
> Affects Versions: 2.6.0
> Reporter: Karthik Kambatla
> Assignee: Rohith
>
> 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.
