------------------------------
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.
