Amazonka.EMR.ListInstanceGroups
Description
Provides all available details about the instance groups in a cluster.
This operation returns paginated results.
Synopsis
- data ListInstanceGroups = ListInstanceGroups' {}
- newListInstanceGroups :: Text -> ListInstanceGroups
- listInstanceGroups_marker :: Lens' ListInstanceGroups (Maybe Text)
- listInstanceGroups_clusterId :: Lens' ListInstanceGroups Text
- data ListInstanceGroupsResponse = ListInstanceGroupsResponse' {
- marker :: Maybe Text
- instanceGroups :: Maybe [InstanceGroup]
- httpStatus :: Int
- newListInstanceGroupsResponse :: Int -> ListInstanceGroupsResponse
- listInstanceGroupsResponse_marker :: Lens' ListInstanceGroupsResponse (Maybe Text)
- listInstanceGroupsResponse_instanceGroups :: Lens' ListInstanceGroupsResponse (Maybe [InstanceGroup])
- listInstanceGroupsResponse_httpStatus :: Lens' ListInstanceGroupsResponse Int
Creating a Request

Arguments
| :: Text | |
| -> ListInstanceGroups |
Create a value of ListInstanceGroups with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:marker:ListInstanceGroups', listInstanceGroups_marker - The pagination token that indicates the next set of results to retrieve.
$sel:clusterId:ListInstanceGroups', listInstanceGroups_clusterId - The identifier of the cluster for which to list the instance groups.
