Subject [jira] [Created] (YARN-87) NM ResourceLocalizationService can fail to create
Date Wed, 05 Sep 2012 22:22:09 GMT
Jason Lowe created YARN-87:
------------------------------

             Summary: NM ResourceLocalizationService can fail to create 
                 Key: YARN-87
                 URL: https://issues.apache.org/jira/browse/YARN-87
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 2.1.0-alpha, 0.23.3
            Reporter: Jason Lowe
            Assignee: Jason Lowe
            Priority: Critical


{{ResourceLocalizationService}} creates a file cache and user cache directory when it starts
up but doesn't specify the permissions for them when they are created.  If the cluster configs
are set to limit the default permissions (e.g.: fs.permissions.umask-mode=0077 instead of
the default 0022), then the cache directories are created with too-restrictive permissions
and no jobs are able to run.
