It uses the zookeeper leader election so only the node that is the
master is active, anyone else is in slave mode.

Also mind that zk requires a running quorum to function, eg so if you
have 3, you need 51%+ to be up and running, eg 2 nodes.
So if you lose 2 nodes, and only have 1 then zk is in zombie mode
(cant recall what they call this situation) and wont function, you
need to bring up at least 1 more node to have a quorum.
