Xiang Li updated HBASE-20186:
-----------------------------
    Description: 
In RSGroupBasedLoadBalancer
{code}
public List<RegionPlan> balanceCluster(Map<ServerName, List<RegionInfo>> 
clusterState)
{code}


for (Address sName : info.getServers()) {
  for(ServerName curr: clusterState.keySet()) {
    if(curr.getAddress().equals(sName)) {
      groupClusterState.put(curr, correctedState.get(curr));
    }
  }
}

  was:
In {
public List<RegionPlan> balanceCluster(Map<ServerName, List<RegionInfo>> 
clusterState)}

for (Address sName : info.getServers()) {
  for(ServerName curr: clusterState.keySet()) {
    if(curr.getAddress().equals(sName)) {
      groupClusterState.put(curr, correctedState.get(curr));
    }
  }
}
