> {{ResourceLocalizationService}} creates a file cache and user cache directory when it starts up but doesn't specify the permissions for them when they are created.  If the cluster configs are set to limit the default permissions (e.g.: fs.permissions.umask-mode=0077 instead of the default 0022), then the cache directories are created with too-restrictive permissions and no jobs are able to run.
