Subject [jira] [Commented] (HADOOP-7602) wordcount, sort etc on har files fails with NPE
Date Wed, 14 Sep 2011 17:55:09 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7602?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13104719#comment-13104719

Jitendra Nath Pandey commented on HADOOP-7602:

  I am ok with throwing exceptions in SecurityUtil methods instead of empty strings. One caveat
is that these are public methods, changing signature could cause incompatibility. 
  I believed that canonical service name could be a more generic concept used in many contexts,
therefore I have been reluctant to tie it down to only tokens. But as of now canonical service
name is used only for token service currently, therefore returning null if token not supported
should be ok. But again this is a public API, returning null is a semantic difference and
may cause issues in applications already using this method and expecting a string back in
all cases. 
  It may be unlikely that these methods are actually being used by any application, but these
are part of public APIs so the compatibility point needs to be thought through.
