> When a table is range-partitioned, or stats partitioned, it is possible that the amount of the data hosted at each region server may not be uniform.  Assume region server s running on node n hosts more data than the rest of the region servers. With the current ESP co-location assignment,  node s will be assigned with more # of ESPs.
