CfnStepProps

class aws_cdk.aws_emr.CfnStepProps(*, action_on_failure, hadoop_jar_step, job_flow_id, name)

Bases: object

Properties for defining a CfnStep.

Parameters:

action_on_failure (str) – This specifies what action to take when the cluster step fails. Possible values are CANCEL_AND_WAIT and CONTINUE .
hadoop_jar_step (Union[IResolvable, HadoopJarStepConfigProperty, Dict[str, Any]]) – The HadoopJarStepConfig property type specifies a job flow step consisting of a JAR file whose main function will be executed. The main function submits a job for the cluster to execute as a step on the master node, and then waits for the job to finish or fail before executing subsequent steps.
job_flow_id (str) – A string that uniquely identifies the cluster (job flow).
name (str) – The name of the cluster step.

Attributes

action_on_failure

This specifies what action to take when the cluster step fails.

Possible values are CANCEL_AND_WAIT and CONTINUE .

hadoop_jar_step

The HadoopJarStepConfig property type specifies a job flow step consisting of a JAR file whose main function will be executed.

The main function submits a job for the cluster to execute as a step on the master node, and then waits for the job to finish or fail before executing subsequent steps.

job_flow_id

A string that uniquely identifies the cluster (job flow).

name

The name of the cluster step.
