John George commented on HADOOP-7602:
-------------------------------------
>
> If {{buildDTServiceAuthority}} ever returns an empty string, then the token
> is
> rendered useless. The logs will show that a token was acquired, but
> connections will mysteriously fail because an empty string doesn't match the
> address of the connection.
The logs are buggy then?
>
> The 1-line fix for the real problem is equally as minimal as reintroducing a
> bug to mask another bug.

What you are saying here "might" be true, but my point is that in a sustaining
release, it is better to minimize changes to known issues (as opposed to fixing
everything around it) - just because it is safer that way.
Having said that, I will still upload another patch with the changes you
suggested
> wordcount, sort etc on har files fails with NPE
