> Key: HADOOP-13627
> URL: https://issues.apache.org/jira/browse/HADOOP-13627

> Issue Type: Sub-task
> Components: security
> Affects Versions: 2.7.3

> UGI creates simple IOEs on failure, making it impossible to catch them, ignore them, have smart retry logic around them, etc.
> # Have an explicit exception like {{KerberosAuthException extends IOException}} to raise instead. We can't use {{AuthenticationException}} as that doesn't extend IOE.
> # move {{UGI}}, {{SecurityUtil}} and things related off simple IOEs and into the new one
> # review exceptions raised and consider if they can provide more information
> # for the strings that get created, put them as public static constants, so that tests can look for them explicitly —tests that don't break if the text is changed.
> # maybe, {{getUGIFromTicketCache}} to throw this rather than an RTE if no login principals were found (it throws IOEs on login failures, after all)
> # keep KDiag in sync with this
