> JobSubmissionFiles provide getStagingDir to get Staging Directory.If
> stagingArea missing, method will create new directory with this.
> {quote}fs.mkdirs(stagingArea, new FsPermission(JOB_DIR_PERMISSION));{quote}
> It seems create new directory with JOB_DIR_PERMISSION,but this permission
> will be apply by umask.If umask too strict , this permission may be 000(if
> umask is 700).So we should change permission after create.
