@Stability(Stable)
public static interface CfnCluster.PlacementGroupConfigProperty
extends software.amazon.jsii.JsiiSerializable

Placement group configuration for an Amazon EMR cluster.

The configuration specifies the placement strategy that can be applied to instance roles during cluster creation.

To use this configuration, consider attaching managed policy AmazonElasticMapReducePlacementGroupPolicy to the Amazon EMR role.

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.*;
 PlacementGroupConfigProperty placementGroupConfigProperty = PlacementGroupConfigProperty.builder()
         .instanceRole("instanceRole")
         // the properties below are optional
         .placementStrategy("placementStrategy")
         .build();
