-----------------------------------------

             Summary: The balancer shouldn't try balancing one node
                 Key: HBASE-8710

2013-06-07 17:31:47,377 DEBUG [ip-10-20-46-44.novalocal,48569,1370640098134-BalancerChore]
balancer.StochasticLoadBalancer: Could not find a better load balance plan.  Tried 3200 different
configurations in 27ms, and did not find anything with a computed cost less than 25.0

Ideally we'd not even try one configuration, let alone 3.2k.
