RSGroupInfoManagerImpl (Apache HBase

java.lang.Object
- org.apache.hadoop.hbase.rsgroup.RSGroupInfoManagerImpl

所有已实现的接口:

ServerListener, RSGroupInfoManager
```
public class RSGroupInfoManagerImpl
extends Object
implements RSGroupInfoManager, ServerListener
```
This is an implementation of RSGroupInfoManager. Which makes use of an HBase table as the persistence store for the group information. It also makes use of zookeeper to store group information needed for bootstrapping during offline mode.
