Biju Nair updated HBASE-17499:
------------------------------
Component/s: Balancer
> 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
> Components: Balancer
> 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.
