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

I believe HBASE-17624 makes servers ordered by hostname then port as it 
provides compareTo() in Address class, as follow. Please correct me if I am 
wrong here.
{code}
  @Override
  public int compareTo(Address that) {
    int compare = this.getHostname().compareTo(that.getHostname());
    if (compare != 0) return compare;
    return this.getPort() - that.getPort();
  }
{code}

> Regarding the output of the command of "get_rsgoup" in hbase shell, or the 
> section of "Server Group" of HMaster's web UI, the tables are not sorted, so 
> not quite easy to read, like:
> {code}
> hbase(main):003:0> get_rsgroup 'default'
> GROUP INFORMATION
> ...
> Tables:
> table3
> ns2:table22
> table1
> ns1:table11
> ...
> {code}
> They could be sorted in the order of namespace then table name:
> {code}
> table1
> table3
> ns1:table11
> ns2:table22
> {code}
