Enabling 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 the 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.
