> As Lars sugested in WHIRR-170:
> The user should "be able to optionally control the order (services start). This could be role based and specified like so
> {code}
> whirr.role-order=zk,nn+jt,dn+tt,hbase-master,hbase-regionserver
> {code}
> If not specified the system should make any effort to start the services as quickly as possible, for example in multiple threads. In other words, when the role-order is not given no guarantee about order can be given."
