Description

The Queue Info is configured in fair-scheduler.xml like below

<queue name="root">
     <queue name="deva">
         <minResources>3072mb,3vcores</minResources>
        <maxResources>4096mb,4vcores</maxResources>
         <queue name="sample">
              <minResources>1024mb,1vcores</minResources>
             <maxResources>2048mb,2vcores</maxResources>
              <aclSubmitApps>Charlie</aclSubmitApps>
          </queue>
      </queue>
     <queue name="deva">
          <minResources>1024mb,1vcores</minResources>
          <maxResources>2048mb,2vcores</maxResources>
      </queue>
</allocations>

The Queue root.deva configured last will override existing root.deva in root.deva.sample, like the attachment 

 root.deva

Used Resources:	<memory:0, vCores:0>
Min Resources:	<memory:1024, vCores:1>.  => should be <3072mb,3vcores>
Max Resources:	<memory:2048, vCores:2>.  => should be <4096mb,4vcores>
Reserved Resources:	<memory:0, vCores:0>
Steady Fair Share:	<memory:1024, vCores:2>
Instantaneous Fair Share:	<memory:0, vCores:0>

 
root.deva.sample

Min Resources:	<memory:1024, vCores:1>
Max Resources:	<memory:2048, vCores:2>
Reserved Resources:	<memory:0, vCores:0>
Steady Fair Share:	<memory:1024, vCores:2>
