Keith Turner commented on ACCUMULO-2149:
----------------------------------------
bq. Would it be sufficient to have the verification MR job look at the job
counters to verify that the number of data local map tasks are within some
threshold of the total number of launched map tasks?
That sounds like a good check. Not as rigorous as I would like, but much
better than nothing. If there is a bug in the Accumulo code and its giving
the wrong location for a tablet, then M/R would report task as local that are
not. For example if Accumulo was giving M/R the last location instead of the
current location.
