             Summary: Bound the total heap memory used for the rolling average of RegionLoads
                 Key: HBASE-17499
                 URL: https://issues.apache.org/jira/browse/HBASE-17499
             Project: HBase
          Issue Type: Improvement
            Reporter: Ted Yu


Currently "hbase.master.balancer.stochastic.numRegionLoadsToRemember" controls the number of RegionLoads which are kept by StochasticLoadBalancer for each region.

The parameter doesn't take into account the number of regions in the cluster.
Meaning, the amount of heap consumed by RegionLoads would be out of norm for cluster with large number of regions.

This issue is to see if we should bound the total heap memory used for the rolling average of RegionLoads.
