Review comment:

function calls.
Well, it's a tradeoff indeed. I would still favour code isolation from
specific impl logic, over the single additional call. Here we are making the
code a bit tighter, with one more place to be changed in the event of a change
at _HFileSystem_, for example. If we agree to get this merged though, can we
at least make sure we have tests for the two _if_ conditions now?
