Jitendra Nath Pandey commented on HADOOP-7602:
----------------------------------------------
Comparing the latest patch with the earliest patch that John had, I am more
inclined towards the earlier approach. The point is that the methods
buildDTService and buildDTAuthority in SecurityUtil are public utility methods
but are not handling the invalid input well. In some cases they do return empty
string host, but not consistently. I think better approach is to make that
behavior consistent. In most common case when these methods are called with an
invalid input, the caller code doesn't really care about what they return. For
example, calling buildDTService for har file system.
> wordcount, sort etc on har files fails with NPE
