Hi,

First I build a 3 nodes cluster (A,B,C) with zk.reconfig commands.

Now we stop the all the ZK, and we make a new cluster (A,B,D) configured
with the same ports.

In that scenario, if you start C, it will join the ensemble, becoming
(A,B,C,D).
The problem is that it's not the same ensemble, C shouldn't have been
allowed to join the new ensemble.

Is there a way to prevent this from happening? (even if it's hacky)

Thanks,
Ben
