It is possible to imagine a number of scenarios, including that, but also
needing to build with new hadoop versions ( can't loose build from scratch ).
There are a number of things we can do down the road.
I think this work is going to help people enough in the near term to land
it, while we discuss longer term refactoring and workflow.
