// Use `InstanceFleetConfig` to define instance fleets for an EMR cluster.
//
// A cluster can not use both instance fleets and instance groups. For more information, see [Configure Instance Fleets](https://docs.aws.amazon.com//emr/latest/ManagementGuide/emr-instance-group-configuration.html) in the *Amazon EMR Management Guide* .
//
// > The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.
//
// Example:
//   // The code below shows an example of how to instantiate this type.
//   // The values are placeholders you should change.

	// The target capacity of On-Demand units for the instance fleet, which determines how many On-Demand instances to provision.
	//
	// When the instance fleet launches, Amazon EMR tries to provision On-Demand instances as specified by `InstanceTypeConfig` . Each instance configuration has a specified `WeightedCapacity` . When an On-Demand instance is provisioned, the `WeightedCapacity` units count toward the target capacity. Amazon EMR provisions instances until the target capacity is totally fulfilled, even if this results in an overage. For example, if there are 2 units remaining to fulfill capacity, and Amazon EMR can only provision an instance with a `WeightedCapacity` of 5 units, the instance is provisioned, and the target capacity is exceeded by 3 units.
	//
	// > If not specified or set to 0, only Spot instances are provisioned for the instance fleet using `TargetSpotCapacity` . At least one of `TargetSpotCapacity` and `TargetOnDemandCapacity` should be greater than 0. For a master instance fleet, only one of `TargetSpotCapacity` and `TargetOnDemandCapacity` can be specified, and its value must be 1.
