Review Comment:
Actually , I am now thinking I don't see any use-case where you would turn
off any of these from making a key. What do you think? From user point of
view, probably simpler is better and we should have reasonable defaults.
Maybe we could have a configurable key but just limit it to to add
additional hive conf if we missed something, as a safety valve. In any case,
without dynamic loading, the user cant add additional code suppliers like ugi,
and thus is limited to just setting config values here.
