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. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
