Deleting an Auto Scaling Policy - DeleteAutoScalingPolicy

Function

This API is used to delete the autoscaling policy of a specified MRS cluster. After deletion, cluster will no longer automatically scale nodes based on the rules. Confirm your business requirements before proceeding.

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.
