> {{DefaultContainerExecutor}} can fail to set the proper permissions on its local directories
if the cluster has been configured with a restrictive umask, e.g.: fs.permissions.umask-mode=0077.
 The configured umask ends up defeating the permissions requested by {{DefaultContainerExecutor}}
when it creates directories.
