I don't know, I'm a huge fan of consensus for service discovery. It would be quite the kick in the pants if I thought that I had drained a group of machines and started some destructive maintenance on them, only to find that the eventual consistency fairy had forgotten about a couple of them, causing 500s on the site... Multi-DC zookeeper isn't untenable. I've done it before with a quorum spread across five datacenters.

It's certainly possible to run zookeeper across multiple datacenters at scale as yelp has demonstrated, however we've elected to make a different set of tradeoffs. Our goals include reducing operational complexity and being able to minimize the impact of node failures, i.e. quickly remove them from consideration by clients.
