Jacques Nadeau commented on PARQUET-328:
----------------------------------------
I'm not sure about how other frameworks use Parquet... but in the case of
Drill, we already have the FS object since we're doing a bunch of stuff. (As
such, this method requires us to convert back into a conf so that it can be
converted into an FS again.)
