> Key: YARN-108
> URL: https://issues.apache.org/jira/browse/YARN-108
> Project: Hadoop YARN
> Issue Type: Bug
> Components: nodemanager
> Affects Versions: 0.23.3, 2.0.0-alpha
> Reporter: Jason Lowe
> Assignee: Jason Lowe
> Priority: Critical
> Attachments: YARN-108.patch
>
>
> When the cluster is configured with a restrictive umask, e.g.:
> {{fs.permissions.umask-mode=0077}}, the nodemanager can end up creating
> directory entries in the public cache with the wrong permissions. The
> permissions can end up where only the nodemanager user can access files in
> the public cache, preventing jobs from running properly.
