Delete queues

You must first stop the queue before deleting the queue. You can delete a single queue and also parent queue and its children if all the queues in the hierarchy are stopped.

In Capacity Scheduler, parent queues, child queues, and the root queue can all be stopped. For an application to be accepted at any child queue, all the queues in the hierarchy all the way up to the root queue must be running. This means that if a parent queue is stopped, all of the descendant queues in that hierarchy are inactive, even if their own state is RUNNING.

  1. In Cloudera Manager, select Clusters > YARN Queue Manager UI service. A graphical queue hierarchy is displayed in the Overview tab.
  2. Click on the three vertical dots on the queue and select Delete Queue .

    You can use the Delete Queues and its Children option to delete both parent queue and its children queues.

  3. You will be prompted for a confirmation. Click OK to stop the queue.
