Re: How do we find the Server the client is connected to?
That detail is purposefully not exposed through the client api, however it is output to the log on connection establishment. Why would your client code need to know which server in the ensemble it is connected to? Patrick Rob Baccus wrote: How do I determine the server the client is connected to? It is not exposed as far as I can see in either the ZooKeep object or the ClentCnxn object. I did find on line 790 in ClientCnxn.StartConnect() method the place the actual server connection is happening but that is not exposed. Rob Baccus 425-201-3812

Re: How do we find the Server the client is connected to?
It's possible, but not pretty. Try this: 1) create a subclass of ZooKeeper to be used in your tests 2) in the subclass add something like this: public String getConnectedServer() { return ((SocketChannel)cnxn.sendThread.sockKey.channel()).socket() .getInetAddress().toString(); } Feel free to add a JIRA, I think we could make this a protected method on ZooKeeper to make testing easier (and not expose internals).

Re: How do we find the Server the client is connected to?
Possible, but very ugly. I do something similar to this in zk tests: org.apache.zookeeper.server.quorum.QuorumPeerMainTest.testBadPeerAddressInQuorum() if you want to see an example.
