> I'm seeing the following behavior:
> - set RPC timeout to a short value
> - call next() for some batch of rows, big enough so the client times out before the result
is returned
> - the HConnectionManager stuff will retry the next() call to the same server. At this
point, one of two things can happen: 1) the previous next() call will still be processing,
in which case you get a LeaseException, because it was removed from the map during the processing,
or 2) the next() call will succeed but skip the prior batch of rows.
