A Step Functions Task to create an EMR Cluster.

The ClusterConfiguration is defined as Parameters in the state machine definition.

OUTPUT: the ClusterId.

Example: 

 Role clusterRole = Role.Builder.create(this, "ClusterRole")
         .assumedBy(new ServicePrincipal("ec2.amazonaws.com"))
         .build();
 Role serviceRole = Role.Builder.create(this, "ServiceRole")
         .assumedBy(new ServicePrincipal("elasticmapreduce.amazonaws.com"))
         .build();
 Role autoScalingRole = Role.Builder.create(this, "AutoScalingRole")
         .assumedBy(new ServicePrincipal("elasticmapreduce.amazonaws.com"))
         .build();
 autoScalingRole.assumeRolePolicy.addStatements(
 PolicyStatement.Builder.create()
         .effect(Effect.ALLOW)
         .principals(List.of(
             new ServicePrincipal("application-autoscaling.amazonaws.com")))
         .actions(List.of("sts:AssumeRole"))
         .build());
 EmrCreateCluster.Builder.create(this, "Create Cluster")
         .instances(InstancesConfigProperty.builder().build())
         .clusterRole(clusterRole)
         .name(TaskInput.fromJsonPathAt("$.ClusterName").getValue())
         .serviceRole(serviceRole)
         .autoScalingRole(autoScalingRole)
         .build();
