Sean Busbey commented on ACCUMULO-4335:
---------------------------------------

very least, non-zero for error should be a guaranteed outcome. I think this
would also be helpful for some of the Apache Slider work (helpful in
determining what to do downstream).
indeed. :) I ran into this with an ops problem that at first appeared to be "my
watchdog isn't working!"
