Update scheduler-conf corrupts the CS configuration when removing queue which is referred in queue mapping.  The deletion is failed with below error message but the queue got removed and job submission failed but not removed from the ZKConfigurationStore. On subsequent modify using scheduler-conf, the queue appears again from ZKConfigurationStore

*Repro:*

{code}
1. Setup Queue Mapping

yarn.scheduler.capacity.root.queues=default,dummy
yarn.scheduler.capacity.queue-mappings=g:hadoop:dummy

2. Stop the root.dummy queue

<update-queue>
       <queue-name>root.dummy</queue-name>
       <params>
         <entry>
           <key>state</key>
           <value>STOPPED</value>
         </entry>
       </params>
     </update-queue>
	 
	 
3. Delete the root.dummy queue

curl --negotiate -u : -X PUT -d @abc.xml -H "Content-type: application/xml" 'http://<RM_IP>:8088/ws/v1/cluster/scheduler-conf?user.name=yarn'

<sched-conf>
      <update-queue>
          <queue-name>root.default</queue-name>
          <params>
            <entry>
              <key>capacity</key>
              <value>100</value>
            </entry>
          </params>
        </update-queue>

        <remove-queue>root.dummy</remove-queue>
      </sched-conf>
