Subject Re: Query ZK through a REST i/f
Date Thu, 10 Mar 2016 21:49:17 GMT
I am running ZK version 3.4.8 which is the most latest stable release of
ZK. The log4j has
zookeeper.log.dir=.
zookeeper.log.file=zookeeper.log
but i don't see zookeeper.log being generated anywhere within my container.
Unicasted some more details to you.

Thanks
