Use InstanceGroupConfig to define instance groups for an EMR cluster.

A cluster can not use both instance groups and instance fleets. For more information, see Create a Cluster with Instance Fleets or Uniform Instance Groups in the Amazon EMR Management Guide .

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.*;
 ConfigurationProperty configurationProperty_;
