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 that a step will be canceled, even if the request is successfully submitted.
When you use Amazon EMR releases 5.28.0 and later, you can cancel steps that are in
a PENDING or RUNNING state. In earlier versions of Amazon EMR, you can
only cancel steps that are in a PENDING state.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginCancelSteps and EndCancelSteps.
