Based on the predefined expressions of the dynamic placement rule, dynamic queues are created automatically during runtime .
YARN supports only one level of dynamic leaf queues. You can view the queue properties of the dynamically created leaf queues in the Dynamic Auto-Creation of Queue section of the Queue Properties. You can configure the dynamic leaf-queue properties by clicking on the Edit Child Queues option of its managed parent queue. The queue properties set at the managed parent queue level is applied to all of its leaf queues. For more information about setting properties for dynamic leaf queues, see Configure dynamic queue properties.
A leaf icon is displayed next to the queue name for dynamically created leaf-queues.
