You can delete a tenant that is not required on MRS Manager.

A tenant has been added.
You have checked whether the tenant to be deleted has sub-tenants. If the tenant has sub-tenants, delete them; otherwise, you cannot delete the tenant.
The role of the tenant to be deleted cannot be associated with any user or user group. For details about how to cancel the binding between a role and a user, see Modifying User Information.

On MRS Manager, click Tenant.
In the tenant list on the left, move the cursor to the tenant node to be deleted and click Delete.
The Delete Tenant dialog box is displayed. If you want to save the tenant data, select Reserve the data of this tenant. Otherwise, the tenant's storage space will be deleted.
Click OK to save the settings.
It takes a few minutes to save the configuration. After the tenant is deleted successfully, the role and storage space of the tenant are also deleted.
- After the tenant is deleted, the task queue of the tenant still exists in Yarn.
- If you choose not to reserve data when deleting the parent tenant, data of sub-tenants is also deleted if the sub-tenants use storage resources.
