I find a way to stop zk nodes peacefully under Windows.
If you start zk nodes in order of 1,2,3
then you should stop them in reverse order, i.e. 3,2,1
Thus you can stop process peacefully without any errors.
Hope this help people!

I think those zk server warning messages are expected. Until you have 3
running instances you don't have a "Quorum" and the Zookeeper instances
complain. Once the third one comes up they are "happy" and don't complain
any more. You'd get similar messages if one of the Zookeeper nodes ever
went down.
As for the stopping of zk server - I've never had any problem issuing a
stop command, but I'm running Linux so I may not be much good to you in
that regard.
