I think refactoring HS2 so that we can plugin other services that want to provide a jdbc/odbc api makes a lot of sense.
There is a lot investment that has gone into HS2 in terms of authentication modes support (including kerberos), transport mode options, transport encryption, and more recently load balancing and rolling upgrade support through the zookeeper service discovery feature. And ofcourse, there are also the jdbc driver. There are also proprietary odbc drivers ( available for free download). It doesn't make sense to write that over and over!
