Add queues using YARN Queue Manager UI
You can add queues to the predefined queue called root from the Yarn Queue Manager UI. The Capacity Scheduler has a predefined queue called root. All queues in the system are children of the root queue. Each child queue is tied to its parent queue, but children queues do not inherit properties directly from the parent queue unless otherwise specified.

- Weight allocation mode: Enter the name of the queue and the fraction of the resource of the resource in the Configured Weight for the queue.
You can continue to add more parent and child queues by following the same steps.
