public class JobFlowInstancesConfig
extends Object
implements Serializable, Cloneable, StructuredPojo
```
A description of the Amazon EC2 instance on which the cluster (job flow) runs. A valid JobFlowInstancesConfig must contain either InstanceGroups or InstanceFleets. They cannot be used together. You may also have MasterInstanceType, SlaveInstanceType, and InstanceCount (all three must be present), but we don't recommend this configuration.

    The instance fleet configuration is available only in Amazon EMR versions 4.8.0 and later, excluding 5.0.x versions.
    
    NOTE: This method appends the values to the existing list (if any). Use setEc2SubnetIds(java.util.Collection) or withEc2SubnetIds(java.util.Collection) if you want to override the existing values.
    
    Parameters:
    
    ec2SubnetIds - Applies to clusters that use the instance fleet configuration. When multiple EC2 subnet IDs are specified, Amazon EMR evaluates them and launches instances in the optimal subnet.
