Creating a Resource Pool

Updated at: Mar 25, 2021 GMT+08:00

Scenario

In an MRS cluster, users can logically divide Yarn cluster nodes to combine multiple NodeManagers into a Yarn resource pool. Each NodeManager belongs to one resource pool only. The system contains a Default resource pool by default. All NodeManagers that are not added to customized resource pools belong to this resource pool.

You can create a customized resource pool on MRS Manager and add hosts that have not been added to other customized resource pools to it.

Procedure

  1. On MRS Manager, click Tenant.
  2. Click the Resource Pools tab.
  3. Click Add Resource Pool.
  4. In Create Resource Pool, set the properties of the resource pool.

    • Name: Enter a name for the resource pool. The name of the newly created resource pool cannot be Default.

      The name consists of 1 to 20 characters and can contain digits, letters, and underscores (_) but cannot start with an underscore (_).

    • Hosts: In the host list on the left, select the name of a specified host and click to add the selected host to the resource pool. Only hosts in the cluster can be selected. The host list of a resource pool can be left blank.

  5. Click OK.
  6. After a resource pool is created, users can view the Name, Members, Type, vCore and Memory in the resource pool list. Hosts that are added to the customized resource pool are no longer members of the Default resource pool.
