所有已实现的接口:

ClusterMetrics

已过时。
As of release 2.0.0, this will be removed in HBase 3.0.0 Use ClusterMetrics instead.

@InterfaceAudience.Public

public class ClusterStatus
extends Object
implements ClusterMetrics
```
Status information on the HBase cluster.
ClusterStatus provides clients with information such as:
- The count and names of region servers in the cluster.
- The count and names of dead region servers in the cluster.
- The name of the active master for the cluster.
- The name(s) of the backup master(s) for the cluster, if they exist.
- The average cluster load.
- The number of regions deployed on the cluster.
- The number of requests since last report.
- Detailed region server loading and resource usage information, per server and per region.
- Regions in transition at master
- The unique cluster ID
ClusterMetrics.Option provides a way to get desired ClusterStatus information. The following codes will get all the cluster information.
```
 
 // Original version still works
 Admin admin = connection.getAdmin();
 ClusterStatus status = admin.getClusterStatus();
 // or below, a new version which has the same effects
 ClusterStatus status = admin.getClusterStatus(EnumSet.allOf(Option.class));
 
 
```
If information about live servers is the only wanted. then codes in the following way:
```
 
 Admin admin = connection.getAdmin();
 ClusterStatus status = admin.getClusterStatus(EnumSet.of(Option.LIVE_SERVERS));
 
 
```
