             Summary: Fix Balancer in 1.3 not moving regions off overloaded regionserver
                 Key: HBASE-15504
                 URL: https://issues.apache.org/jira/browse/HBASE-15504
             Project: HBase
          Issue Type: Bug
            Reporter: Elliott Clark


We pushed 1.3 to a couple of clusters. In some cases the regions were assigned VERY un-evenly and the regions would not move after that.

We ended up with one rs getting thousands of regions and most servers getting 0. Running balancer would do nothing. The balancer would say that it couldn't find a solution with less than the current cost.
