--------------------------------------------------------------

 DNS queries should be case insensitive is OK, but at master will compare the hostname 。but
when we compare HostName it can't be equals。
like:
 public boolean containsServer(HostAndPort hostPort) {
    return servers.contains(hostPort);
  }

> I migrated rs-group in 1.1.2version,and found regionserver host is different between
zk and meta table. 
> For example, host BeiJIN.98.100.hbase.com In zk or master is beijin.98.100.hbase.com
, but in meter table  is BeiJIN.98.199.hbase.com. 
> Because of this , when rsgroup balance compare host , that cause problem 。 
> And i found when regionserver report host to master , it will make the hostname to lowcase。
