Flavio Junqueira commented on ZOOKEEPER-1659:
---------------------------------------------

I'm aware of deployments that use HQS. However, the main general concern I have 
is that the other day I tried to implement a new quorum verifier and a lot of 
tests failed. It seems that there are parts of the code base, especially tests, 
that are hardcoding majorities, which I find a bit annoying. It would be great 
if we could keep the use of quorums independent of the actual implementation, 
and in this particular case rely on the QuorumVerifier interface.
