> 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.
