Queue ACLs should be refreshed without requiring a restart of the job tracker
-----------------------------------------------------------------------------

                 Key: HADOOP-5396
                 URL: https://issues.apache.org/jira/browse/HADOOP-5396
             Project: Hadoop Core
          Issue Type: Improvement
          Components: mapred
            Reporter: Hemanth Yamijala


In large shared deployments of the M/R clusters, it is normal that new users will periodically
want to get access to some queues on the M/R framework. Requiring a JT restart for each such
change is operationally inconvenient and seems an overkill. There should be a way for updating
ACLs with new users without requiring a JT restart.
