Description

Currently HBase SLB doesn't know about the physical capacity of region servers and assumes that all the servers in the cluster are of same capacity. But in reality cluster will have servers with different configuration. It will be a good improvement if SLB can take into account the variations in  the capacity of different servers. Note that there is another ticket HBASE-11780 similar to this to handle heterogenous clusters but to add a resource based load balancer.
