org.apache.hadoop.hbase.master.balancer.StochasticLoadBalancer.CostFromRegionLoadFunction

org.apache.hadoop.hbase.master.balancer.StochasticLoadBalancer.MemstoreSizeCostFunction

Enclosing class:

StochasticLoadBalancer

public static class StochasticLoadBalancer.MemstoreSizeCostFunction
extends StochasticLoadBalancer.CostFromRegionLoadFunction

Compute the cost of total memstore size. The more unbalanced the higher the computed cost will be. This uses a rolling average of regionload.
