Amazonka.EMR.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 CLI automatically paginates results to return a list greater than 50 steps. To return more than 50 steps using the CLI, specify a Marker, which is a pagination token that indicates the next set of steps to retrieve.

This operation returns paginated results.

Creating a Request

data ListSteps

This input determines which steps to list.

See: newListSteps smart constructor.

ListSteps'

Fields

• marker :: Maybe Text

  The maximum number of steps that a single ListSteps action returns is 50. To return a longer list of steps, use multiple ListSteps actions along with the Marker parameter, which is a pagination token that indicates the next set of results to retrieve.

• stepIds :: Maybe [Text]

  The filter to limit the step list based on the identifier of the steps. You can specify a maximum of ten Step IDs. The character constraint applies to the overall length of the array.

• stepStates :: Maybe [StepState]

  The filter to limit the step list based on certain states.

• clusterId :: Text

  The identifier of the cluster for which to list the steps.

newListSteps

Arguments

:: Text

$sel:clusterId:ListSteps'

-> ListSteps

Create a value of ListSteps with all optional fields omitted.

Use generic-lens or optics to modify other optional fields.

The following record fields are available, with the corresponding lenses provided for backwards compatibility:

ListSteps, listSteps_marker - The maximum number of steps that a single ListSteps action returns is 50. To return a longer list of steps, use multiple ListSteps actions along with the Marker parameter, which is a pagination token that indicates the next set of results to retrieve.

$sel:stepIds:ListSteps', listSteps_stepIds - The filter to limit the step list based on the identifier of the steps. You can specify a maximum of ten Step IDs. The character constraint applies to the overall length of the array.

$sel:stepStates:ListSteps', listSteps_stepStates - The filter to limit the step list based on certain states.

$sel:clusterId:ListSteps', listSteps_clusterId - The identifier of the cluster for which to list the steps.
