Subject Re: Query regarding Zookeeper Windows API start/stop, using Zk as a windows service(using prunsrv)
Date Tue, 18 Mar 2014 15:52:13 GMT
Hi Patrick,

Thanks for the reply and encouragement.
Will fix it  soon and patch against trunk

One more thing
cannot connect to http://irc.freenode.org/ so the link
http://zookeeper.apache.org/irc.html is leading the user no where.

Thanks,
Nandini
