Network.AWS.EMR.ListInstances

Provides information about the cluster instances that Amazon EMR provisions on behalf of a user when it creates the cluster. For example, this operation indicates when the EC2 instances reach the Ready state, when instances become available to Amazon EMR to use for jobs, and the IP addresses for cluster instances, etc.

This operation returns paginated results.

Creating a Request

listInstances

Arguments

:: Text

liClusterId

-> ListInstances

Creates a value of ListInstances with the minimum fields required to make a request.

Use one of the following lenses to modify other fields as desired:

• liInstanceGroupTypes
• liMarker
• liInstanceGroupId
• liClusterId

data ListInstances

This input determines which instances to list.

See: listInstances smart constructor.
