Thanks Cam, It was very helpful and i have setup a cluster of 6 nodes on 2 nodes, with each node having 3 zookeeper servers and they all talk to each other and i could see that.
I could also see that each zookeeper server creates a lots of data and logs which are related to transaction logs and snapshots to maintain high availability in the system. Currently i have configured everything in nodes only but i have read that data & logs should be in separate partition. Can you help on this? Also are there any more performance tuning guidelines available? Regards.
