Zhihong Yu commented on HBASE-5959:
-----------------------------------

{code}
+    double moveCost = computeMoveCost(initialRegionMapping, clusterState);
+    double regionCountSkewCost = 100 * computeSkewLoadCost(clusterState);
+    double tableSkewCost = 50 * computeTableSkewLoadCost(clusterState);
+    double localityCost = 40 * computeDataLocalityCost(clusterState);
{code}
Since the value of move cost varies greatly, the coefficients should be 
designed such that the three latter costs are brought to the same magnitude of 
move cost. Meaning, constant coefficients may not be the best choice.
