----------------------------------

             Summary: Add ServerSsdLocalityCostFunction to StochasticLoadBalancer
                 Key: HBASE-24152
                 URL: https://issues.apache.org/jira/browse/HBASE-24152
             Project: HBase
          Issue Type: New Feature
          Components: Balancer
            Reporter: Zheng Wang
            Assignee: Zheng Wang


When use ONE_SSD storagy policy, or ALL_SSD but has not enough SSD, there will be some hdfs blocks on DISK and others on SSD,so it is reasonable to consider the locality of ssd for StochasticLoadBalancer.
