Daryn Sharp commented on HADOOP-7602:
-------------------------------------
Regarding tests, no matter how this is fixed, you should have one that calls
{{TokenCache.obtainTokensForNamenodes}} with a non-server based authority uri
(ie. a har path) since that's what is breaking.
I consider the pre MR-2780 behavior of {{buildDTServiceAuthority}} is a bug.
The method is not documented as returning an empty string when given bad input.
The {{TokenCache}} should stop erroneously calling it. However, even if the
{{TokenCache}} isn't going to erroneously call the method anymore, I feel there
is still value in having {{buildDTServiceAuthority}} throw on invalid input
instead of returning an invalid value. Otherwise, an invalid return value will
only cause an error to crop up someplace else.
> wordcount, sort etc on har files fails with NPE
