> Ran across a situation where an admin user had accidentally created a directory in one
of the date directories under /mapred/history/done/ that was not readable by the historyserver
user.  That effectively prevented the history server from cleaning any jobs from that date
forward, as it hit an IOException trying to scan the directory and that aborted the entire
clean process.
> The history server should localize IOException handling to the directory/file being processed
and move on to the next entry in the list rather than aborting the entire cleaning process.
