Adding Tags to a Cluster in Batches - BatchCreateClusterTags

Function

This API is used to batch add tags to a specified MRS cluster for cluster classification and management. A cluster can have up to 20 tags. This API is idempotent: duplicate keys are not allowed within the same cluster; if the data already exists, it is overwritten.

Constraints

None

Debugging

You can debug this API in API Explorer. Automatic authentication is supported. API Explorer can automatically generate sample SDK code and supports sample SDK code debugging.

Authorization Information

Each account has all the permissions required to call all APIs, but IAM users must be assigned the required permissions.

  • If you are using role/policy-based authorization, see Permissions Policies and Supported Actions for details on the required permissions.
  • If you are using identity policy-based authorization, no identity policy-based permissions are required for calling this API.
