```
      The way that individual Amazon EC2 instances terminate when an automatic scale-in activity occurs or an instance group is resized.

This option is only available with Amazon EMR 5.1.0 and later and is the default for clusters created using that version. TERMINATE_AT_TASK_COMPLETION indicates that Amazon EMR blacklists and drains tasks from nodes before terminating the Amazon EC2 instances, regardless of the instance-hour boundary. With either behavior, Amazon EMR removes the least active nodes first and blocks instance termination if it could lead to HDFS corruption. TERMINATE_AT_TASK_COMPLETION is available only in Amazon EMR version 4.1.0 and later, and is the default for versions of Amazon EMR earlier than 5.1.0.

    - targetOnDemandCapacity
```
Integer targetOnDemandCapacity
```
      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. You can use InstanceFleet$ProvisionedOnDemandCapacity to determine the Spot capacity units that have been provisioned for the instance fleet.
      
      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.

TERMINATE_AT_TASK_COMPLETION indicates that Amazon EMR blacklists and drains tasks from nodes before terminating the Amazon EC2 instances, regardless of the instance-hour boundary. With either behavior, Amazon EMR removes the least active nodes first and blocks instance termination if it could lead to HDFS corruption. TERMINATE_AT_TASK_COMPLETION available only in Amazon EMR version 4.1.0 and later, and is the default for versions of Amazon EMR earlier than 5.1.0.

If you do not set this value, the default of 0.18 is used, unless the AmiVersion parameter is set in the RunJobFlow call, in which case the default version of Hadoop for that AMI version is used.
    - ec2SubnetId
```
String ec2SubnetId
```
      Applies to clusters that use the uniform instance group configuration. To launch the cluster in Amazon Virtual Private Cloud (Amazon VPC), set this parameter to the identifier of the Amazon VPC subnet where you want the cluster to launch. If you do not specify this value, the cluster launches in the normal Amazon Web Services cloud, outside of an Amazon VPC, if the account launching the cluster supports EC2 Classic networks in the region where the cluster launches.
      
      Amazon VPC currently does not support cluster compute quadruple extra large (cc1.4xlarge) instances. Thus you cannot specify the cc1.4xlarge instance type for clusters launched in an Amazon VPC.
    - ec2SubnetIds
```

```

      If the AMI supports multiple versions of Hadoop (for example, AMI 1.0 supports both Hadoop 0.18 and 0.20) you can use the JobFlowInstancesConfig HadoopVersion parameter to modify the version of Hadoop from the defaults shown above.
      
      For details about the AMI versions currently supported by Amazon Elastic MapReduce, see AMI Versions Supported in Elastic MapReduce in the Amazon Elastic MapReduce Developer Guide.
      
      Previously, the EMR AMI version API parameter options allowed you to use latest for the latest AMI version rather than specify a numerical value. Some regions no longer support this deprecated option as they only have a newer release label version of EMR, which requires you to specify an EMR release label release (EMR 4.x or later).

    - scaleDownBehavior
```
String scaleDownBehavior
```
      Specifies the way that individual Amazon EC2 instances terminate when an automatic scale-in activity occurs or an instance group is resized. TERMINATE_AT_INSTANCE_HOUR indicates that Amazon EMR terminates nodes at the instance-hour boundary, regardless of when the request to terminate the instance was submitted. This option is only available with Amazon EMR 5.1.0 and later and is the default for clusters created using that version. TERMINATE_AT_TASK_COMPLETION indicates that Amazon EMR blacklists and drains tasks from nodes before terminating the Amazon EC2 instances, regardless of the instance-hour boundary. With either behavior, Amazon EMR removes the least active nodes first and blocks instance termination if it could lead to HDFS corruption. TERMINATE_AT_TASK_COMPLETION available only in Amazon EMR version 4.1.0 and later, and is the default for versions of Amazon EMR earlier than 5.1.0.

Integer scalingAdjustment
```
      The amount by which to scale in or scale out, based on the specified AdjustmentType. A positive value adds to the instance group's EC2 instance count while a negative number removes instances. If AdjustmentType is set to EXACT_CAPACITY, the number should only be a positive integer. If AdjustmentType is set to PERCENT_CHANGE_IN_CAPACITY, the value should express the percentage as a decimal. For example, -0.20 indicates a decrease in 20% increments of cluster capacity.
    - coolDown
```
Integer coolDown
```
      The amount of time, in seconds, after a scaling activity completes before any further trigger-related scaling activities can start. The default value is 0.
- Class com.amazonaws.services.elasticmapreduce.model.SpotProvisioningSpecification extends Object implements Serializable
  - Serialized Fields
    - timeoutDurationMinutes
```
Integer timeoutDurationMinutes
```
      The spot provisioning timeout period in minutes. If Spot instances are not provisioned within this time period, the TimeOutAction is taken. Minimum value is 5 and maximum value is 1440. The timeout applies only during initial provisioning, when the cluster is first created.
    - timeoutAction
```
String timeoutAction
```
      The action to take when TargetSpotCapacity has not been fulfilled when the TimeoutDurationMinutes has expired. Spot instances are not uprovisioned within the Spot provisioining timeout. Valid values are TERMINATE_CLUSTER and SWITCH_TO_ON_DEMAND to fulfill the remaining capacity.
    - blockDurationMinutes
```
Integer blockDurationMinutes
```
      The defined duration for Spot instances (also known as Spot blocks) in minutes. When specified, the Spot instance does not terminate before the defined duration expires, and defined duration pricing for Spot instances applies. Valid values are 60, 120, 180, 240, 300, or 360. The duration period starts as soon as a Spot instance receives its instance ID. At the end of the duration, Amazon EC2 marks the Spot instance for termination and provides a Spot instance termination notice, which gives the instance a two-minute warning before it terminates.
