> 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.
