Luke Brassard commented on ACCUMULO-1830:
-----------------------------------------
[~kturner], it's worth noting that we think that this was fixed with the
resolution in this ticket. The main reason for the comment from yesterday was
to provide more insight where this sort of behavior could be seen.
Also, we believe that no pertinent data was actually lost in the scenario
outlined above. The Accumulo errors may indicate that data is lost, since it
reports that an RFile is missing, but the RFile was actually deleted in a safe
way.
