Subject RE: Query regarding Zookeeper Windows API start/stop, using Zk as awindows service(using prunsrv)
Date Sun, 16 Mar 2014 22:21:54 GMT
Same. Haven't had problems with start and stop scripts.  Would suggest reverting and taking
another look.

I run regularly on Windows 8 and I haven't been having any issues with the scripts.

Hi Nandini, this is great feedback. It's likely that not many people
are using ZK and those cmd scripts on windows. As a result things get
stale. I'd encourage you to provide some patches agains the trunk
which incorporate your fixes. You can see more detail on how to do
that here:

Regards,

Patrick
