   This PR piqued my interest. :)
   
   First off, I'm glad to see we're fixing the use of the deprecated `HTables` and HBase APIs, so that's fantastic.  Thanks for the effort on this @nickwallen .
   
   I will say, however, that I was surprised at the size of a single PR until I looked.  This PR seems to be a mix of:
   * Dependency changes for HBase 2.0.2
   * Rearchitecture/code abstraction rewriting (e.g. your point 11)
   * Replacing the deprecated API calls
   * Deprecating features
   
   I have some concerns about this approach.  Conflating so many things inside of a PR which is already inherently risky seems to increase the risk multiplicatively.  It is also difficult to review, I'd say.
   
   I would suggest that these three separate concerns be split across 3 separate PRs:
   * Replacing deprecated API calls against `master`
     * This is also a decent time to, instead of replacing the mistake of passing around `HTableInterface` to create a key-value store abstraction which you can pass around instead that supports scan, get and put.
   * Dependency changes for HBase 2.0.2 against this feature branch
   * Deprecating features
     * As I said in a previous comment, only after a community discussion and I'd strongly suggest it be separate from the upgrade.
   * Rearchitecture/code abstraction rewriting against `master` *after* the HDP upgrade has landed.
   
   As I say, please don't take my feedback as an indication that I don't appreciate the work that went into this.  There is much good here, but there is just..well..very much here. :)
