ClusterStatus (Apache HBase - Client 1.7.2 API)

java.lang.Object
- org.apache.hadoop.io.VersionedWritable
- - org.apache.hadoop.hbase.ClusterStatus

所有已实现的接口:

org.apache.hadoop.io.Writable
```
@InterfaceAudience.Public
@InterfaceStability.Evolving
public class ClusterStatus
extends org.apache.hadoop.io.VersionedWritable
```
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
