> {{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.
