Two things:

1) Hadoop is the wrong technology. It's not designed to support
transactional operations.

2) Transactional operations are, in general, your Big Obstacle for doing
anything in the way of a distributed storage manager.

It's possible you could make both of the above "go away" if you were
planning for a DW platform in which transactions weren't important.
However, that would have to become an incompatible fork of PostgreSQL.

AFAIK, the Yahoo platform does not involve Hadoop at all.
