Re: [Zookeeper-user] FW: Client Connect Exceptions + Zookeeper Unit Tests fail

The only thing I see different is that you seem to be using an old version
of zookeeper on apache. Can you download trunk from

http://svn.apache.org/repos/asf/hadoop/zookeeper/trunk

And try it again? 

The print statement --
³Trying to connect² is not there in the code any more.  Can you try the
trunk so that the log information matches the current code in the trunk and
easier to debug.
