-------------------------------------------
Jeez, you right. Nice catch, Arshad! I focused too much on the content and
totally forgot this "little" detail. :( Thanks for the patch!
> Make the three-node minimum more explicit in documentation and on website

> 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.
