@Generated(value="jsii-pacmak/1.104.0 (build e79254c)", date="2024-11-27T16:50:57.795Z") @Stability(Stable) public class CfnStep extends CfnResource implements IInspectable
Use Step to specify a cluster (job flow) step, which runs only on the master node.

Steps are used to submit data processing jobs to a cluster.

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.emr.*;
 CfnStep cfnStep = CfnStep.Builder.create(this, "MyCfnStep")
         .actionOnFailure("actionOnFailure")
         .hadoopJarStep(HadoopJarStepConfigProperty.builder()
                 .jar("jar")
                 // the properties below are optional
                 .args(List.of("args"))
                 .mainClass("mainClass")
                 .stepProperties(List.of(KeyValueProperty.builder()
                         .key("key")
                         .value("value")
                         .build()))
                 .build())
         .jobFlowId("jobFlowId")
         .name("name")
         .build();
