See the RunJobFlow API for complete documentation on input parameters

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 ‘$’)

  • result_selector (Optional[Mapping[str, Any]]) – The JSON that will replace the state’s raw result and become the effective result before ResultPath is applied. You can use ResultSelector to create a payload with values that are static or selected from the state’s raw result. Default: - None

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

  • instances (InstancesConfigProperty) – A specification of the number and type of Amazon EC2 instances.

  • name (str) – The Name of the Cluster.

  • additional_info (Optional[str]) – A JSON string for selecting additional features. Default: - None

  • applications (Optional[Sequence[ApplicationConfigProperty]]) – A case-insensitive list of applications for Amazon EMR to install and configure when launching the cluster. Default: - EMR selected default

  • cluster_role (Optional[IRole]) – Also called instance profile and EC2 role. An IAM role for an EMR cluster. The EC2 instances of the cluster assume this role. This attribute has been renamed from jobFlowRole to clusterRole to align with other ERM/StepFunction integration parameters. Default: - - A Role will be created

  • configurations (Optional[Sequence[ConfigurationProperty]]) – The list of configurations supplied for the EMR cluster you are creating. Default: - None

  • ebs_root_volume_size (Optional[Size]) – The size of the EBS root device volume of the Linux AMI that is used for each EC2 instance. Default: - EMR selected default

  • kerberos_attributes (Optional[KerberosAttributesProperty]) – Attributes for Kerberos configuration when Kerberos authentication is enabled using a security configuration. Default: - None

  • log_uri (Optional[str]) – The location in Amazon S3 to write the log files of the job flow. Default: - None

  • release_label (Optional[str]) – The Amazon EMR release label, which determines the version of open-source application packages installed on the cluster. Default: - EMR selected default

  • scale_down_behavior (Optional[EmrClusterScaleDownBehavior]) – Specifies the way that individual Amazon EC2 instances terminate when an automatic scale-in activity occurs or an instance group is resized. Default: - EMR selected default

  • security_configuration (Optional[str]) – The name of a security configuration to apply to the cluster. Default: - None

  • service_role (Optional[IRole]) – The IAM role that will be assumed by the Amazon EMR service to access AWS resources on your behalf. Default: - A role will be created that Amazon EMR service can assume.

  • tags (Optional[Mapping[str, str]]) – A list of tags to associate with a cluster and propagate to Amazon EC2 instances. Default: - None

  • visible_to_all_users (Optional[bool]) – A value of true indicates that all IAM users in the AWS account can perform cluster actions if they have the proper IAM policy permissions. Default: true
