Having done a project or two with Zookeeper, I vowed never to go near it
again.  To be fair, that was a couple of years ago, but between reading the
source code and being able to quickly spot bugs, and an unstable and
problematic NodeJS integration, I wound up doing more to keep code at arm's
length from it than anything else (I ended up writing a small Java "lock
server" backed by Zookeeper that used open HTTP connections as locks [the
url was what to lock] that could be redundantly to several servers lock
servers, so the Node code didn't have to know or care about Zookeeper).

It works, but I wouldn't use it again without a gun to my head.

Another potentially interesting alternative I haven't used in production
but will give a shot to the next time I need something like it is etcd:
