Failed to View MRS Cluster Details

Symptom

A user fails to access the cluster details page by clicking the cluster name on the MRS console.

Cause Analysis

1. The user's MRS cluster uses enterprise project A (with MRS FULLACCESS and ECS FULLACCESS permissions).
2. The VPC uses enterprise project B.
3. The security group uses enterprise project A.
4. No permissions are configured for the IAM user group.
5. The analysis shows that enterprise project B used by the user's VPC does not have the vpc readonly permission. As a result, the error is reported.

Procedure

Add the vpc readonly permission to the enterprise project used by the VPC.
