>             Project: HBase
>          Issue Type: Improvement
>            Reporter: Ted Yu
>            Priority: Major
>              Labels: balancer
>
> 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.
