JobFlowInstancesConfig is a property of the AWS::EMR::Cluster resource.

JobFlowInstancesConfig defines the instance groups or instance fleets that comprise the cluster. JobFlowInstancesConfig must contain either InstanceFleetConfig or InstanceGroupConfig . They cannot be used together.

You can now define task instance groups or task instance fleets using the TaskInstanceGroups and TaskInstanceFleets subproperties. Using these subproperties reduces delays in provisioning task nodes compared to specifying task nodes with the InstanceFleetConfig and InstanceGroupConfig resources.

Example:

 // The code below shows an example of how to instantiate this type.
 // The values are placeholders you should change.
 import software.amazon.awscdk.services.emr.*;
 ConfigurationProperty configurationProperty_;

- getEc2SubnetId
  
  @Stability(Stable) @Nullable default String getEc2SubnetId()
  
  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 and your account supports EC2-Classic, the cluster launches in EC2-Classic.
  See Also:

- getEc2SubnetIds
  
  @Stability(Stable) @Nullable default List<String> getEc2SubnetIds()
  
  Applies to clusters that use the instance fleet configuration.
  When multiple Amazon EC2 subnet IDs are specified, Amazon EMR evaluates them and launches instances in the optimal subnet.
  
  The instance fleet configuration is available only in Amazon EMR releases 4.8.0 and later, excluding 5.0.x versions.

- getHadoopVersion
  
  @Stability(Stable) @Nullable default String getHadoopVersion()
  
  Applies only to Amazon EMR release versions earlier than 4.0. The Hadoop version for the cluster. Valid inputs are "0.18" (no longer maintained), "0.20" (no longer maintained), "0.20.205" (no longer maintained), "1.0.3", "2.2.0", or "2.4.0". 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.

- getTaskInstanceFleets
  
  @Stability(Stable) @Nullable default Object getTaskInstanceFleets()
  
  Describes the EC2 instances and instance configurations for the task instance fleets when using clusters with the instance fleet configuration.
  These task instance fleets are added to the cluster as part of the cluster launch. Each task instance fleet must have a unique name specified so that CloudFormation can differentiate between the task instance fleets.
  
  You can currently specify only one task instance fleet for a cluster. After creating the cluster, you can only modify the mutable properties of InstanceFleetConfig , which are TargetOnDemandCapacity and TargetSpotCapacity . Modifying any other property results in cluster replacement. > To allow a maximum of 30 Amazon EC2 instance types per fleet, include TaskInstanceFleets when you create your cluster. If you create your cluster without TaskInstanceFleets , Amazon EMR uses its default allocation strategy, which allows for a maximum of five Amazon EC2 instance types.

  @Stability(Stable) @Nullable default Object getTaskInstanceGroups()
  
  Describes the EC2 instances and instance configurations for task instance groups when using clusters with the uniform instance group configuration.
  These task instance groups are added to the cluster as part of the cluster launch. Each task instance group must have a unique name specified so that CloudFormation can differentiate between the task instance groups.
