Subject Re: Running Zookeeper in 2 machines
Date Tue, 05 Nov 2013 04:52:51 GMT
You need a minimum of 3 ZK instances to have any redundancy, because when
an instance fails the remaining instances need to be able to form a quorum.
To do this, more than half of the instances need to be able to communicate
with each other.

You can certainly run multiple instances on a single host though if that's
what you want, you just need to modify the configuration so that the ports
don't conflict between instances.
cheers
