Wei Yan created YARN-2669:
-----------------------------

             Summary: FairScheduler: print out a warning log when users 
provider a queueName starting with "root." in the allocation.xml
                 Key: YARN-2669
                 URL: https://issues.apache.org/jira/browse/YARN-2669
             Project: Hadoop YARN
          Issue Type: Improvement
            Reporter: Wei Yan
            Assignee: Wei Yan
            Priority: Minor


For an allocation file like:
{noformat}
<allocations>
  <queue name="root.q1">
    <minResources>4096mb,4vcores</minResources>
  </queue>
</allocations>
{noformat}

Users may wish to config minResources for a queue with full path "root.q1". 
However, right now, fair scheduler will treat this configureation for the queue 
with full name "root.root.q1". We need to print out a warning msg to notify 
users about this.
