> URL: https://issues.apache.org/jira/browse/YARN-4365
> Project: Hadoop YARN
> Issue Type: Bug

> Affects Versions: 2.7.2
> Reporter: Jason Lowe

>
> If the namenode is in safe mode for some reason then FileSystemNodeLabelStore
> will prevent the RM from starting since it unconditionally tries to create
> the root directory for the label store. If the root directory already exists
> and no labels are changing then we shouldn't prevent the RM from starting
> even if the namenode is in safe mode.
