Thanks Cam, So i should have either 2+1 or 3+2 Zookeeper servers on these tow nodes to which both nodes are talking?
In this case, what should i put in zoo.cfg file for host values as currently i am using localhost at both nodes. server.1=localhost:2888:3888 server.1=localhost:2889:3889 server.1=localhost:28908:3890 Again how these 3 nodes will form a cluster?
