If anything we'd move methods in. So far we've been strict and not leak implementation details
into the interface.
It might be prudent in the end to remove some methods from the HTable implementation and make
the functionality available through the HConnection only.

File a jira, Nick? We can discuss there.

HTableInterface is marked with:



It would be tricky if we move some methods out.
