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.
