> The concept of ZooKeeper is really an implementation detail and should not be exposed in the {{HConnection}} interface.   Therefore, I suggest removing the {{HConnection.getZooKeeperWrapper()}} method from the interface. 
> I couldn't find any uses of this method within the HBase code base except for in one of the unit tests: {{org.apache.hadoop.hbase.TestZooKeeper}}.  This unit test should be changed to instantiate the implementation of {{HConnection}} directly, allowing it to use the {{getZooKeeperWrapper()}} method.  This requires making {{org.apache.hadoop.hbase.client.HConnectionManager.TableServers}} public.  (I actually think TableServers should be moved out into an outer class, but in the spirit of small patches, I'll refrain from suggesting that in this issue).
> I'll attach a patch for:
> # The removal of {{HConnection.getZooKeeperWrapper()}}
> # Change of {{TableServers}} class from private to public
> # Direct instantiation of {{TableServers}} within {{TestZooKeeper}}.
