    Description

      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 from CS configuration and job submission failed and not removed from the backend ZKConfigurationStore. On subsequent modify using scheduler-conf, the queue appears again from ZKConfigurationStore

      Repro:

      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>
