# SetKeepJobFlowAliveWhenNoSteps
<a name="API_SetKeepJobFlowAliveWhenNoSteps"></a>

You can use the `SetKeepJobFlowAliveWhenNoSteps` to configure a cluster (job flow) to terminate after the step execution, i.e., all your steps are executed. If you want a transient cluster that shuts down after the last of the current executing steps are completed, you can configure `SetKeepJobFlowAliveWhenNoSteps` to false. If you want a long running cluster, configure `SetKeepJobFlowAliveWhenNoSteps` to true.

For more information, see [Managing Cluster Termination](https://docs.aws.amazon.com/emr/latest/ManagementGuide/UsingEMR_TerminationProtection.html) in the *Amazon EMR Management Guide*.
