Hi,

I just download zk 3.4.4 to my ubuntu 10.04 and zkServer.sh start and
zkCli.sh to connect. But got a KeeperException. It says
ConnectionLoss. I viewed the log, NIOServerCnxn caught end of stream
exception. Can anyone give me some advice?

Here's the zookeeper.out:

Hi Wang,

This looks like the same issue being discussed here:

http://mail-archives.apache.org/mod_mbox/zookeeper-user/201209.mbox/%3Ck3t8hh%24tak%241%40ger.gmane.org%3E

I think people are working on fixing this in 3.4.5.

Thanks!
