Configuring Cloud Service Permissions
The MapReduce Service (MRS) console can interact with MRS clusters to provide related functions and monitor cluster status. Permission assignment is required when you use MRS for the first time.
After permission assignment, MRS creates an agency named mrs_admin_agency in Identity and Access Management (IAM). After the agency is created, do not modify or delete it. Deleting the agency or the Tenant Administrator role in the agency will automatically cancel the permission assignment. If permission assignment is canceled, functions such as cluster creation, cluster scale-in/out, Master node specification upgrade, auto scaling, cluster name modification, and IAM user synchronization will be affected, and the cluster running status cannot be monitored.
Procedure
- Log in to the management console.
- Choose Analytics > MapReduce Service in the service list. The Assign Permissions page is displayed.
Figure 1 Assigning permissions
- Click Assign.
After assignment is agreed, an agency named mrs_admin_agency will be created in IAM. Do not modify or delete the agency after it is created. After the agency is created, you can use MRS.
After assignment, if the agency fails to be created, it is probably because the number of agencies already reaches the upper limit. In this case, log in to the IAM console and delete unnecessary agencies, or contact the administrator to increase the agency quota.
