@adyach this patch's goal is to make sure when ever a new connection is
being established DNS lookup will be performed. If you have given a hostname in
connection string then if the underlying IP is gone the TCP connection will
break and new TCP connection will be attempted by Zookeeper code and at this
time DNS lookup will again be performed.
I hope this helps if you can post your example of connection string it will
be more helpful. Zookeeper connection string is supposed to contain the ZK
ensemble set/subset hostnames/ips.
