This is a good thing to build. In addition, though, it'd be interesting to also try out building
a module on top of Phoenix (a "SQL skin" on HBase that uses the java client API directly to
transform SQL queries into an optimized run plan, including server-side optimizations using
coprocessors). This should be independent of the direct HBase module (which doesn't require
use of Phoenix on the HBase cluster), but would be a compelling addition. It's also possible
this could be done just with the existing JDBC mm module, but there are some differences from
standard SQL (like the use of UPSERT instead of INSERT and UPDATE) that might require a specialized
module (perhaps a subclass of the jdbc version).
