This represents a step in a cluster.
Contents
- ActionOnFailure
-
The action to take when the cluster step fails. Possible values are
TERMINATE_CLUSTER,CANCEL_AND_WAIT, andCONTINUE.TERMINATE_JOB_FLOWis provided for backward compatibility. We recommend usingTERMINATE_CLUSTERinstead.If a cluster's
StepConcurrencyLevelis greater than1, do not useAddJobFlowStepsto submit a step with this parameter set toCANCEL_AND_WAITorTERMINATE_CLUSTER. The step is not submitted and the action fails with a message that theActionOnFailuresetting is not valid.If you change a cluster's
StepConcurrencyLevelto be greater than 1 while a step is running, theActionOnFailureparameter may not behave as you expect. In this case, for a step that fails with this parameter set toCANCEL_AND_WAIT, pending steps and the running step are not canceled; for a step that fails with this parameter set toTERMINATE_CLUSTER, the cluster does not terminate.Type: String
Valid Values:
TERMINATE_JOB_FLOW | TERMINATE_CLUSTER | CANCEL_AND_WAIT | CONTINUERequired: No
- Config
-
The Hadoop job configuration of the cluster step.
Type: HadoopStepConfig object
Required: No
- ExecutionRoleArn
-
The Amazon Resource Name (ARN) of the runtime role for a step on the cluster. The runtime role can be a cross-account IAM role. The runtime role ARN is a combination of account ID, role name, and role type using the following format:
arn:partition:service:region:account:resource.For example,
arn:aws:IAM::1234567890:role/ReadOnlyis a correctly formatted runtime role ARN.Type: String
Length Constraints: Minimum length of 0. Maximum length of 2048.

Type: String
Required: No
- Name
-
