CfnClusterPropsMixin Mixin ​

The AWS::EMR::Cluster resource specifies an Amazon EMR cluster.

This cluster is a collection of Amazon EC2 instances that run open source big data frameworks and applications to process and analyze vast amounts of data. For more information, see the Amazon EMR Management Guide .

Amazon EMR now supports launching task instance groups and task instance fleets as part of the AWS::EMR::Cluster resource. This can be done by using the JobFlowInstancesConfig property type's TaskInstanceGroups and TaskInstanceFleets subproperties. Using these subproperties reduces delays in provisioning task nodes compared to specifying task nodes with the AWS::EMR::InstanceGroupConfig and AWS::EMR::InstanceFleetConfig resources. Please refer to the examples at the bottom of this page to learn how to use these subproperties.
