Subject Re: 3.3.2 -> 3.4.0 NodeExistsException when reading snapshot
Date Thu, 08 Dec 2011 16:17:04 GMT
Thanks for the responses, guys. In light of the subsequent announcement, we reverted back to
3.3.4 for the time being. Just another data point: When I did try zkCli.sh, it wouldn't even
connect to the server. It looked like this exception prevented it from starting up.
