public class InstanceGroup
extends com.pulumi.resources.CustomResource

Provides an Elastic MapReduce Cluster Instance Group configuration. See [Amazon Elastic MapReduce Documentation](https://aws.amazon.com/documentation/emr/) for more information. > **NOTE:** At this time, Instance Groups cannot be destroyed through the API nor web interface. Instance Groups are destroyed when the EMR Cluster is destroyed. this provider will resize any Instance Group to zero when destroying the resource. ## Example Usage

 
 package generated_program;
 
 import com.pulumi.Context;
 import com.pulumi.Pulumi;
 import com.pulumi.core.Output;
 import com.pulumi.aws.emr.InstanceGroup;
 import com.pulumi.aws.emr.InstanceGroupArgs;
 import java.util.ArrayList;
 import java.util.Arrays;
 import java.util.Map;
 import java.io.File;
 import java.nio.file.Files;
 import java.nio.file.Paths;
 
 public class App {
     public static void main(String[] args) {
         Pulumi.run(App::stack);
     }
 
     public static void stack(Context ctx) {
         var task = new InstanceGroup("task", InstanceGroupArgs.builder()
             .clusterId(tf_test_cluster.id())
             .instanceCount(1)
             .instanceType("m5.xlarge")
             .name("my little instance group")
             .build());
 
     }
 }

## Import Using `pulumi import`, import EMR task instance group using their EMR Cluster ID and Instance Group ID separated by a forward-slash `/`. For example: ```sh $ pulumi import aws:emr/instanceGroup:InstanceGroup task_group j-123456ABCDEF/ig-15EK4O09RZLNR ```

                     @Nullable
                     com.pulumi.resources.CustomResourceOptions options)
```

Method Detail

autoscalingPolicy
```
public com.pulumi.core.Output<java.util.Optional<java.lang.String>> autoscalingPolicy()
```
Returns:

The Auto Scaling policy document. This is a JSON formatted string. See [EMR Auto Scaling](https://docs.aws.amazon.com/emr/latest/ManagementGuide/emr-automatic-scaling.html)

bidPrice
```
public com.pulumi.core.Output<java.util.Optional<java.lang.String>> bidPrice()
```
Returns:

If set, the bid price for each EC2 instance in the instance group, expressed in USD. By setting this attribute, the instance group is being declared as a Spot Instance, and will implicitly create a Spot request. Leave this blank to use On-Demand Instances.

clusterId
```
public com.pulumi.core.Output<java.lang.String> clusterId()
```
Returns:

ID of the EMR Cluster to attach to. Changing this forces a new resource to be created.

configurationsJson

public com.pulumi.core.Output<java.util.Optional<java.lang.String>> configurationsJson()

Returns:

A JSON string for supplying list of configurations specific to the EMR instance group. Note that this can only be changed when using EMR release 5.21 or later.

ebsOptimized
```
public com.pulumi.core.Output<java.util.Optional<java.lang.Boolean>> ebsOptimized()
```
Returns:

Indicates whether an Amazon EBS volume is EBS-optimized. Changing this forces a new resource to be created.

```
Returns:

Human friendly name given to the instance group. Changing this forces a new resource to be created.

region
```
public com.pulumi.core.Output<java.lang.String> region()
```
Returns:

Region where this resource will be [managed](https://docs.aws.amazon.com/general/latest/gr/rande.html#regional-endpoints). Defaults to the Region set in the provider configuration.

runningInstanceCount
```

Returns:

The number of instances currently running in this instance group.

public com.pulumi.core.Output<java.lang.String> status()

Returns:: The current status of the instance group.

get

public static InstanceGroup get(java.lang.String name,
                                com.pulumi.core.Output<java.lang.String> id,
                                @Nullable
