        # ==== Parameters
        # * JobFlowId <~String> - A string that uniquely identifies the job flow
        # * Steps <~Array> - A list of steps to be executed by the job flow
        #   * 'ActionOnFailure'<~String> - TERMINATE_JOB_FLOW | CANCEL_AND_WAIT | CONTINUE Specifies the action to take if the job flow step fails
