Subject Re: Interesting bug report

While we want to be fault tolerant, there's a point where we want to
eventually fail. I know we have a couple never ending retry loops that need
to be addressed (https://issues.apache.org/jira/browse/ACCUMULO-1268), but
I'm unsure if queries suffer from this problem.

Unfortunately, fault tolerance is a bit at odds with instant notification
of system issues, since some of the fault tolerance is temporally oriented.
And that ticket lacks context of it never failing out vs. failing out
eventually (but too long for the user)
