ListSteps

Provides a list of steps for the cluster in reverse order unless you specify stepIds with the request or filter by StepStates. You can specify a maximum of 10 stepIDs. The AWS CLI automatically paginates results to return a list greater than 50 steps. To return more than 50 steps using the AWS CLI, specify a Marker, which is a pagination token that indicates the next set of steps to retrieve.
