---------------------------------------
Summary: Make the three-node minimum more explicit in
documentation and on website
Key: ZOOKEEPER-2240
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-2240
Project: ZooKeeper
Issue Type: Improvement
Components: documentation
Reporter: Shawn Heisey
Priority: Minor
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.
