Thank you for the tip Rakesh, it's indeed very helpful. So after checking the ZK instances with the "stat" command the two instances seem to be working fine, one as a leader and the other one as a follower. However this was achieved only by stopping both instances and having the quorum unavailable for a little while. When i try to add the second instance without restarting/stopping the first it doesn't really work, because the first is still in standalone mode: $ echo stat | nc ZK1 9983 Zookeeper version: 3.4.5-1392090, built on 09/30/2012 17:52 GMT Clients: /<ZK1 IP>:35517[0](queued=0,recved=1,sent=0)
Latency min/avg/max: 0/0/0 Received: 7 Sent: 6 Connections: 1 Outstanding: 0 Zxid: 0x0 Mode: standalone Node count: 4 and the second replies to the stat command with a: $ echo stat | nc ZK2 9983 This ZooKeeper instance is not currently serving requests Is there a way to commute from standalone mode to quorum without compromising availability?
