listSteps method

Future<ListStepsOutput> listSteps({ required String clusterId, String? marker, List<String>? stepIds, List<StepState>? stepStates, })

Provides a list of steps for the cluster in reverse order unless you specify stepIds with the request of filter by StepStates. You can specify a maximum of ten stepIDs.

May throw InternalServerException. May throw InvalidRequestException.

Parameter clusterId : The identifier of the cluster for which to list the steps.

Parameter marker : The pagination token that indicates the next set of results to retrieve.

Parameter 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.

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

Implementation

Future<ListStepsOutput> listSteps({
  required String clusterId,
  String? marker,
  List<String>? stepIds,
  List<StepState>? stepStates,
}) async {
  ArgumentError.checkNotNull(clusterId, 'clusterId');
  final headers = <String, String>{
    'Content-Type': 'application/x-amz-json-1.1',
    'X-Amz-Target': 'ElasticMapReduce.ListSteps'
  };
  final jsonResponse = await _protocol.send(
    method: 'POST',
    requestUri: '/',
    exceptionFnMap: _exceptionFns,
    // TODO queryParams
    headers: headers,
    payload: {
      'ClusterId': clusterId,
      if (marker != null) 'Marker': marker,
      if (stepIds != null) 'StepIds': stepIds,
      if (stepStates != null)
        'StepStates': stepStates.map((e) => e.toValue()).toList(),
    },
  );

  return ListStepsOutput.fromJson(jsonResponse.body);
