Properties for EmrAddStep.

Parameters
  • comment (Optional[str]) – An optional description for this state. Default: - No comment

  • heartbeat (Optional[Duration]) – Timeout for the heartbeat. Default: - None

  • input_path (Optional[str]) – JSONPath expression to select part of the state to be the input to this state. May also be the special value JsonPath.DISCARD, which will cause the effective input to be the empty object {}. Default: - The entire task input (JSON path ‘$’)

  • integration_pattern (Optional[IntegrationPattern]) – AWS Step Functions integrates with services directly in the Amazon States Language. You can control these AWS services using service integration patterns Default: IntegrationPattern.REQUEST_RESPONSE

  • output_path (Optional[str]) – JSONPath expression to select select a portion of the state output to pass to the next state. May also be the special value JsonPath.DISCARD, which will cause the effective output to be the empty object {}. Default: - The entire JSON node determined by the state input, the task result, and resultPath is passed to the next state (JSON path ‘$’)

  • result_path (Optional[str]) – JSONPath expression to indicate where to inject the state’s output. May also be the special value JsonPath.DISCARD, which will cause the state’s input to become its output. Default: - Replaces the entire input with the result (JSON path ‘$’)

  • timeout (Optional[Duration]) – Timeout for the state machine. Default: - None

  • cluster_id (str) – The ClusterId to add the Step to.

  • jar (str) – A path to a JAR file run during the step.

  • name (str) – The name of the Step.

  • action_on_failure (Optional[ActionOnFailure]) – The action to take when the cluster step fails. Default: ActionOnFailure.CONTINUE

  • args (Optional[List[str]]) – A list of command line arguments passed to the JAR file’s main function when executed. Default: - No args

  • main_class (Optional[str]) – The name of the main class in the specified Java file. If not specified, the JAR file should specify a Main-Class in its manifest file. Default: - No mainClass

  • properties (Optional[Mapping[str, str]]) – A list of Java properties that are set when the step runs. You can use these properties to pass key value pairs to your main function. Default: - No properties
