Implements IMixin

Extends Mixin

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 .

You can currently only add task instance groups to a cluster with this resource. If you use this resource, CloudFormation waits for the cluster launch to complete before adding the task instance group to the cluster. In order to add task instance groups to the cluster as part of the cluster launch and minimize delays in provisioning task nodes, use the TaskInstanceGroups subproperty for the AWS::EMR::Cluster JobFlowInstancesConfig property instead. To use this subproperty, see AWS::EMR::Cluster for examples.
