Nathan Roberts commented on HADOOP-7602:
----------------------------------------
Yes. I like the idea of only changing getCanonicalServiceName within the har fs
and then have the TokenCache skip that filesystem when gathering tokens. This
seems like the least risky change. We can address the fact that
buildDTServiceName needs a better way than NPE to indicate there is a problem
in the ip->host jira or another one altogether. If someone besides HAR is going
to run into the NPE, it's clear they're doing something wrong so it wouldn't
necessarily be a bad thing to track them down even if it's via NPE.
> wordcount, sort etc on har files fails with NPE
