Subject Re: anyone relying on hadoop1 still?

Yes. Hoya (which I think recently got renamed, but might be wrong there) is
running HBase inside various Yarn containers as a Yarn application. Idea
would be that yarn is the fabric for managing your entire cluster and you
just run various yarn apps, e.g. mapreduce, HBase, hive, etc
