Deleting a Tenant

Scenario

You can delete tenants that are no longer used on MRS Manager based on service requirements to release resources occupied by the tenants.

Prerequisites

  • A tenant has been added.
  • The tenant has no sub-tenants. If the tenant has sub-tenants, delete them; otherwise, the tenant cannot be deleted.
  • The role of the tenant is not associated with any user or user group.

Procedure

  1. Log in to MRS Manager and choose Tenant Resources.
  2. In the tenant list on the left, click the target tenant and click .

    • If you want to retain the tenant data, select Reserve the data of this tenant resource. Otherwise, the storage space of the tenant will be deleted.
    • To delete a tenant without retaining the tenant data as a user who does not belong to the supergroup, you should first log in to the HDFS client as a user who belongs to the supergroup and then manually clear the storage space of that tenant to avoid residual data.

  3. Click OK.

    It takes a few minutes to save the configuration. After the tenant is deleted, the role and storage space of the tenant are also deleted.

    After the tenant is deleted, the queue of the tenant still exists in Yarn. The queue of the tenant is not displayed on the role management page in Yarn.
