Modify queue configuration format and parsing to support a hierarchy of queues.
-------------------------------------------------------------------------------

                 Key: MAPREDUCE-861
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-861
             Project: Hadoop Map/Reduce
          Issue Type: Sub-task
            Reporter: Hemanth Yamijala


MAPREDUCE-853 proposes to introduce a hierarchy of queues into the Map/Reduce framework. This
JIRA is for defining changes to the configuration related to queues. 

The current format for defining a queue and its properties is as follows: mapred.queue.<queue-name>.<property-name>.
For e.g. mapred.queue.<queue-name>.acl-submit-job. The reason for using this verbose
format was to be able to reuse the Configuration parser in Hadoop. However, administrators
currently using the queue configuration have already indicated a very strong desire for a
more manageable format. Since, this becomes more unwieldy with hierarchical queues, the time
may be good to introduce a new format for representing queue configuration.
