Network.AWS.EMR.ListClusters
Description
Provides the status of all clusters visible to this AWS account. Allows you to filter the list of clusters based on certain criteria; for example, filtering by cluster creation date and time or by status. This call returns a maximum of 50 clusters per call, but returns a marker to track the paging of the cluster list across multiple ListClusters calls.
See: AWS API Reference for ListClusters.
This operation returns paginated results.
- listClusters :: ListClusters
- data ListClusters
- lcCreatedAfter :: Lens' ListClusters (Maybe UTCTime)
- lcMarker :: Lens' ListClusters (Maybe Text)
- lcClusterStates :: Lens' ListClusters [ClusterState]
- lcCreatedBefore :: Lens' ListClusters (Maybe UTCTime)
- listClustersResponse :: Int -> ListClustersResponse
- data ListClustersResponse
- lcrsMarker :: Lens' ListClustersResponse (Maybe Text)
- lcrsClusters :: Lens' ListClustersResponse [ClusterSummary]
- lcrsResponseStatus :: Lens' ListClustersResponse Int
Creating a Request
listClusters :: ListClusters Source
Creates a value of ListClusters with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data ListClusters Source
This input determines how the ListClusters action filters the list of clusters that it returns.
See: listClusters smart constructor.
Instances
Request Lenses
lcCreatedAfter :: Lens' ListClusters (Maybe UTCTime) Source
The creation date and time beginning value filter for listing clusters .
lcMarker :: Lens' ListClusters (Maybe Text) Source
The pagination token that indicates the next set of results to retrieve.
lcClusterStates :: Lens' ListClusters [ClusterState] Source
The cluster state filters to apply when listing clusters.
lcCreatedBefore :: Lens' ListClusters (Maybe UTCTime) Source
The creation date and time end value filter for listing clusters .
Destructuring the Response
Arguments
| :: Int | |
| -> ListClustersResponse |
Creates a value of ListClustersResponse with the minimum fields required to make a request.
Use one of the following lenses to modify other fields as desired:
data ListClustersResponse Source
This contains a ClusterSummaryList with the cluster details; for example, the cluster IDs, names, and status.
See: listClustersResponse smart constructor.
Response Lenses
lcrsMarker :: Lens' ListClustersResponse (Maybe Text) Source
The pagination token that indicates the next set of results to retrieve.
lcrsClusters :: Lens' ListClustersResponse [ClusterSummary] Source
The list of clusters for the account based on the given filters.
lcrsResponseStatus :: Lens' ListClustersResponse Int Source
The response status code.
