Mike Drob commented on ACCUMULO-1672:
-------------------------------------
I feel like there should be a better solution than reducing the number of
tservers. Is this race condition something that can happen on a real cluster? I
would not feel comfortable telling users that the solution is to not run
multiple tablet servers when they just bought several racks of hardware.
Alternatively, is it just an artifact of the way the test is structured?
