> One of the most important parts of a production zookeeper deployment is the three-node minimum requirement for fault tolerance ... but when I glance at the website and the documentation, this requirement is difficult to actually find.
> It is buried deep in the admin documentation, in a sentence that says "Thus, a deployment that consists of three machines can handle one failure, and a deployment of five machines can handle two failures."  Other parts of the documentation hint at it, but nothing that I've seen comes out and explicitly says it.
> Ideally, documentation about this requirement would be in a location where it can be easily pinpointed with a targeted URL, so I can point to ZK documentation with a link and clearly tell SolrCloud users that this is a real requirement.
> If someone can point me to version control locations where I can check out or clone the docs and the website, I'm happy to attempt a patch.
