Provide an ability to refresh queue configuration without restart.
------------------------------------------------------------------

                 Key: MAPREDUCE-893
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-893
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
          Components: jobtracker
            Reporter: Hemanth Yamijala


While administering a cluster using multiple queues, administrators feel a need to refresh
queue properties on the fly without needing to restart the JobTracker. This is partially supported
for some properties such as queue ACLs (HADOOP-5396) and state (HADOOP-5913). The idea is
to extend the facility to refresh other queue properties as well, including scheduler properties.
