Andrei Savu commented on WHIRR-221:
-----------------------------------
Looks great! I'm really happy that you are working on this one.
A few comments:
* on line 51 in ClusterActionHandlerSupport.java I think we want
ImmutableSet.of()
* we need a way to specify a sleep interval between execution stages (we are
going to replace this later with a service status check)
I think we BSD is compatible with ASL. Tom?

> 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."
