Network.AWS.EMR.CancelSteps

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.

Creating a Request

cancelSteps :: CancelSteps

Creates a value of CancelSteps with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• csStepIds - The list of StepIDs to cancel. Use ListSteps to get steps and their states for the specified cluster.
• csClusterId - The ClusterID for which specified steps will be canceled. Use RunJobFlow and ListClusters to get ClusterIDs.

data CancelSteps

The input argument to the CancelSteps operation.

See: cancelSteps smart constructor.

Request Lenses

csStepIds :: Lens' CancelSteps [Text]

cancelStepsResponse

Arguments

:: Int

csrsResponseStatus

-> CancelStepsResponse

Creates a value of CancelStepsResponse with the minimum fields required to make a request.

• csrsResponseStatus - -- | The response status code.

data CancelStepsResponse

The output for the CancelSteps operation.
