I've posted an article on my website that details precisely how to deploy Hadoop 2.0 with Yarn on AWS (or least how I did it, whether or not such an approach will translate to others' circumstances). I had been disappointed that most articles of this type described the process with much older versions of Hadoop or relied on tools like Whirr and I wanted to document and publish my method. Perhaps others will find it useful.
I'm sure others more expert than myself will see opportunities to stream-line or otherwise improve the process. I don't claim that my method is the best, merely that I actually got it to work!
