Properties for Configuring Intra-Queue Preemption

Intra-queue preemption is enabled by default for YARN queues. In addition, you can configure the order of intra-queue preemption either by application priorities or configured user limits.

You must configure the values of the following properties in yarn-site.xml for intra-queue preemption:

Property	Description
`yarn.resourcemanager.monitor.capacity.preemption.intra-queue-preemption.enabled`	Specifies whether intra-queue preemption is enabled or disabled for queues. The default value is `true`.
`yarn.resourcemanager.monitor.capacity.preemption.intra-queue-preemption.preemption-order-policy`	Specifies the order in which a queue can preempt resources. Based on your requirements, you can configure this property to either of the following values: `userlimit-first`, to initiate intra-queue preemption based on configured user limits. This is the default value. `priority-first`, to initiate intra-queue preemption based on application priorities.
