Hi Venkat, If i understood it properly then you are trying to run 3 zookeeper and NN service on one machine. Right? If yes, then one of the major problem is that if unfortunately this machine crashes then you will lose the zookeepers and as a result you cluster will go down. Usually, its recommended to run zookeeper on different machines to avoid cluster failures.
