I've commented on HADOOP-13886 ; I'm not sure that this is a bug in the dynamo
work, more a surfacing of the fact that those internal metrics, while they
helped test what was going on, turn out to be brittle to change. That is what
[~aw] warned me about, so he can be happy that the first people to experience
it is ourselves.
we can cut the test.
