I think that another way to say this is that zkClient is going a bit for the
Spring philosophy that if the caller can't (or won't) be handling the
situation, then they shouldn't be forced to declare it. The Spring
jdbcTemplate is a grand example of the benefits of this.
First implementations of
There is not much way to totally avoid this without massive performance loss
because the connection loss could be during the the time that the
confirmation is returning.
You may be able to tell if the file is yours be examining the content and
ownership, but this is pretty implementation
Not to harp on this ;-) but this sounds like something that would be a
very helpful addition to the README.

That looks really lovely.
Judging by history and that fact that only 40/127 issues are resolved, 3.3
is probably 3-6 months away. Is that a fair assessment?

Yes, that's fair.

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?

Hi all,
I am trying to start zookeeper in two nodes, the configuration file I have
is
tickTime=2000
initLimit=10
syncLimit=5
dataDir=/var/zookeeper
clientPort=2181
server.1=hec-bp1:2888:3888
server.2=hec-bp2:2888:3888
i also have two files /var/zookeeper/myid on each of the machines, the
Grovel the logs.

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()
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.

Hi Hector, looks like a connectivity issue to me: NoRouteToHostException.
3888 is the election port
2888 is the quorum port
basically, the ensemble uses the election port for leader election. Once
a leader is elected it then uses the quorum port for subsequent
communication.
Could it be a
