    Description

      See HBASE-3420. Therein, a wonky cluster had 5k regions on one server and < 1k on others. Balancer ran and wanted to redistribute 3k+ all in one go. Madness.

      If a load of rebalancing to be done, should be done somewhat piecemeal. We need maximum regions to rebalance at a time upper bound at a minimum.
