I am struggling a bit with the ES 2.2 documentation on clustering. Seems like there are many ways of building ES clusters and lots of blog posts out there from different stages of this project's history but a bit hard to find what's a recommended, simple configuration.
I simply want 2 nodes in an active/active configuration that will be easy to scale out horizontally. The ability to auto-scale isn't a requirement. It is to be part of an ELK stack.
