Configuring the Queue Capacity Policy of a Resource Pool

Scenario

After a resource pool is added, you can configure the capacity policy of available resources for Yarn queues so that jobs in the queues can be properly executed in the resource pool. A queue can have the queue capacity policy of only one resource pool.

You can view queues and configure queue capacity policies in any resource pool. After the queue policies are configured, Yarn queues are associated with resource pools.

Prerequisites

A queue has been added, that is, a tenant associated with computing resources has been created.

Procedure

1. Log in to FusionInsight Manager.
2. Choose Tenant Resources > Dynamic Resource Plan.

   The Resource Distribution Policy page is displayed by default.

3. In Resource Pools, select the target resource pool.
4. Locate the row that contains the target resource name in the Resource Allocation area, and click Modify in the Operation column.
5. In the Modify Resource Allocation window, configure the resource capacity policy of the queue in the resource pool.
   • Capacity (%): indicates the percentage of computing resources used by the current tenant.
   • Maximum Capacity (%): indicates the maximum percentage of computing resources used by the current tenant.

6. Click OK.
   

   After the resource capacity values of a queue are deleted and saved, the resource capacity policy of the queue in the resource pool is canceled, indicating that the queue is disassociated from the resource pool. To achieve this, you need to change the default resource pool of the queue to another one. For details, see Configuring a Queue.
