Description

SchedulerConf Mutation API does not Allow Stop and Remove Queue in a single call. The queue has to be stopped before removing and so it is useful to allow both Stop and remove queue in a single call.

Repro:

Capacity-Scheduler.xml:

yarn.scheduler.capacity.root.queues = new, default, dummy
yarn.scheduler.capacity.root.default.capacity = 60
yarn.scheduler.capacity.root.dummy.capacity = 30
yarn.scheduler.capacity.root.new.capacity = 10   


curl -v -X PUT -d @abc.xml -H "Content-type: application/xml" 'http://<RM_IP>:8088/ws/v1/cluster/scheduler-conf'

abc.xml

<sched-conf>
      <update-queue>
          <queue-name>root.default</queue-name>

        </update-queue>
