Subject [jira] [Created] (YARN-108) FSDownload can create cache directories with the wrong permissions
Date Mon, 17 Sep 2012 19:28:07 GMT
Jason Lowe created YARN-108:
-------------------------------

             Summary: FSDownload can create cache directories with the wrong permissions
                 Key: YARN-108
                 URL: https://issues.apache.org/jira/browse/YARN-108
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 0.23.3, 2.0.0-alpha
            Reporter: Jason Lowe
            Assignee: Jason Lowe
            Priority: Critical


When the cluster is configured with a restrictive umask, e.g.: {{fs.permissions.umask-mode=0077}},
the nodemanager can end up creating directory entries in the public cache with the wrong permissions.
 The permissions can end up where only the nodemanager user can access files in the public
cache, preventing jobs from running properly.
