Container for the parameters to the CancelSteps operation. Cancels a pending step or steps in a running cluster. Available only in Amazon EMR versions 4.8.0 and later, excluding version 5.0.0. A maximum of 256 steps are allowed in each CancelSteps request. CancelSteps is idempotent but asynchronous; it does not guarantee a step will be canceled, even if the request is successfully submitted. You can only cancel steps that are in a PENDING state.
