Subject Re: Replacing ZK client with Curator
Date Thu, 28 May 2015 15:35:27 GMT
Hi Devs,

I replaced zookeeper client with curator and ran few tests on real compute
resources, all went well. And tested recovery scenario too. I don't see
connection issues at all after integrate apache curator which we were
seeing time to time in logs. I will merge curator integration branch to
master.

Thanks,
Shameera.
