action_on_failure
instance-attribute
¶
action_on_failure: NotRequired[ActionOnFailure]
The action to take when the cluster step fails. Possible values are TERMINATE_CLUSTER, CANCEL_AND_WAIT, and CONTINUE. TERMINATE_JOB_FLOW is provided for backward compatibility. We recommend using TERMINATE_CLUSTER instead.
If a cluster's StepConcurrencyLevel is greater than 1, do not use AddJobFlowSteps to submit a step with this parameter set to CANCEL_AND_WAIT or TERMINATE_CLUSTER. The step is not submitted and the action fails with a message that the ActionOnFailure setting is not valid.
If you change a cluster's StepConcurrencyLevel to be greater than 1 while a step is running, the ActionOnFailure parameter may not behave as you expect. In this case, for a step that fails with this parameter set to CANCEL_AND_WAIT, pending steps and the running step are not canceled; for a step that fails with this parameter set to TERMINATE_CLUSTER, the cluster does not terminate.
config
instance-attribute
¶
config: NotRequired[HadoopStepConfig]
The Hadoop job configuration of the cluster step.
encryption_key_arn
instance-attribute
¶
encryption_key_arn: NotRequired[String]
The KMS key ARN to encrypt the logs published to the given Amazon S3 destination.
execution_role_arn
instance-attribute
¶
execution_role_arn: NotRequired[OptionalArnType]
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/ReadOnly is a correctly formatted runtime role ARN.
log_uri
instance-attribute
¶
log_uri: NotRequired[String]
The Amazon S3 destination URI for log publishing.
status
instance-attribute
¶
status: NotRequired[StepStatus]
The current execution status details of the cluster step.
