Enable Intra-Queue preemption

Intra-queue preemption prevents resource imbalances in a queue.

Intra-queue preemption helps in effective distribution of resources within a queue based on configured user limits or application priorities.

To configure Intra-Queue Preemption (yarn.resourcemanager.monitor.capacity.preemption.intra-queue-preemption.enabled) on all queues, perform the following:

  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 Scheduler Configuration tab.
  3. Select the Enable Intra Queue Preemption checkbox.
  4. Click Save.

    For information about configuring intra-queue preemption for a specific queue, see Configure Intra-Queue Preemption for a specific queue.
