Description

For an allocation file like:

<allocations>
  <queue name="root.q1">
    <minResources>4096mb,4vcores</minResources>
  </queue>
</allocations>

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.
