// A CloudFormation `AWS::EMR::Cluster`.
//
// 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](https://docs.aws.amazon.com//emr/latest/ManagementGuide/) .
//
// 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.
//
// Example:
// // The code below shows an example of how to instantiate this type.
// // The values are placeholders you should change.
