From an API design standpoint I would rather see a class returned as that
gives more flexibility to evolves the API in the future. This is a lesson I
have learned the hard way. For example if I wanted to add functionality to
get the description of a stat or historical information in the future, that
would mean adding more methods to intstance operations.
I would rather see something like the following for the API.
```java
static interfce TabletServerID {
public String getHost();
public int getPort();
public long getSessionId();
}
static interface TabletServersStatus {
List<TabletServerID> getTabletServers();
Map<String,String> getTabletServerStatus(TabletServerID tsid);
}
TabletServersStatus getTabletServerStatus();
```
