Deleting Tags from a Cluster in Batches - BatchDeleteClusterTags

Function

This API is used to batch delete tags from a specified MRS cluster. A cluster can have up to 20 tags. This API is idempotent: deleting a non-existent tag is handled as a success by default, and no validation is performed on the tag character set range.

The key length is 128 Unicode characters, and the value length is 255 Unicode characters. When deleting, the tags structure must not be missing, and the key must not be empty or an empty string.

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.
