Subject Frequent zookeeper connection loss exception.
Date Wed, 23 Apr 2014 08:06:11 GMT
I am using 3 zookeeper node cluster. In our application we are getting
Connection loss exception frequently even though application doesn't do any
thing special. Now even though if I assume that due to network fluctuations
it might get disconnected and try to connect again , but what I am seeing is
even though application gets connected to one node for some reason it gets
disconnected again tries to connect in another node in ensemble.
