You are looking at the document to setup RM HA manually, which is a very involved process. You want to use the Ambari UI instead to achieve the same goal with much less effort. The following is the instruction on doing it in Ambari. I have done this many time and should not take you more than 10 minutes. After that, you could go back and check all the conf files to understand what has been changed.

I already have a resource manager so what are these "rm1,rm2" values? wouldn't I be using the existing RM id for the one I have ?
