------------------------------------------
Summary: JobSubmissionFiles don't set right permission after mkdirs
Key: MAPREDUCE-7375
URL: https://issues.apache.org/jira/browse/MAPREDUCE-7375
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: mrv2
Affects Versions: 3.3.2
Reporter: Zhang Dongsheng
Attachments: MAPREDUCE-7375.patch
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.
