Network.AWS.EMR.ListClusters

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.

This operation returns paginated results.

Creating a Request

listClusters :: ListClusters

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:

• lcCreatedAfter - The creation date and time beginning value filter for listing clusters.
• lcMarker - The pagination token that indicates the next set of results to retrieve.
• lcClusterStates - The cluster state filters to apply when listing clusters.
• lcCreatedBefore - The creation date and time end value filter for listing clusters.

data ListClusters

This input determines how the ListClusters action filters the list of clusters that it returns.

See: listClusters smart constructor.
