John George commented on HADOOP-7602:
-------------------------------------
> Having {{buildDTServiceName}} return an empty string to satisfy bad behavior
> in the {{TokenCache}} doesn't feel right. I'd prefer an exception like {{new
> IllegalArgumentException( uri + "does not have a server-based authority)}} to
> guard against accidental invocation in the future.
>
I am not knowledgeable enough to decide either way, but the reason that the
above change were made in buildDTServiceName() is because it was doing
something very similar before the changes in MR-2780. If the need to check is
soon going to go away, would it be better to continue what it did before
MR-2780?
