> StochasticLoadBalancer still uses SimpleLoadBalancer's needBalance logic
> ------------------------------------------------------------------------
>
> Key: HBASE-10761
> URL: https://issues.apache.org/jira/browse/HBASE-10761
> Project: HBase
> Issue Type: Bug
> Components: Balancer
> Affects Versions: 0.98.0
> Reporter: Victor Xu
> Attachments: HBASE_10761.patch, HBASE_10761_v2.patch
>
>
> StochasticLoadBalancer has become the default balancer since 0.98.0. But its
> balanceCluster method still uses the BaseLoadBalancer.needBalance() which is
> originally designed for SimpleLoadBalancer. It's all based on the number of
> regions on the regionservers.
> This can cause such a problem: when the cluster has some Hot Spot Region, the
> balance process may not be triggered because the numbers of regions on the
> RegionServers are averaged.
