Subject [jira] Created: (HADOOP-3578) mapred.system.dir should be accessible only to hadoop daemons

mapred.system.dir should be accessible only to hadoop daemons 
--------------------------------------------------------------

                 Key: HADOOP-3578
                 URL: https://issues.apache.org/jira/browse/HADOOP-3578
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
            Reporter: Amar Kamat


Currently the jobclient accesses the {{mapred.system.dir}} to add job details. Hence the {{mapred.system.dir}}
has the permissions of {{rwx-wx-wx}}. This could be a security loophole where the job files
might get overwritten/tampered after the job submission.
