             Summary: Backport HBASE-13965 'Stochastic Load Balancer JMX Metrics' to 0.98
                 Key: HBASE-14289
                 URL: https://issues.apache.org/jira/browse/HBASE-14289
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu
            Assignee: Ted Yu


The default HBase load balancer (the Stochastic load balancer) is cost function based. The cost function weights are tunable but no visibility into those cost function results is directly provided.

This issue backports HBASE-13965 to 0.98 branch to provide visibility via JMX into each cost function of the stochastic load balancer, as well as the overall cost of the balancing plan.
