Subject [jira] [Commented] (HADOOP-7602) wordcount, sort etc on har files fails with NPE
Date Thu, 01 Sep 2011 20:59:12 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13095599#comment-13095599

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.
