Puppet users - Jul 2012 - How to acgieve Inter-Node Dependencies with Puppet?

Hey guys,

I am getting started with puppet and started writing some modules which include
client-server installation model. I was wondering if there is any possibility of
acheving inter-node dependencies using puppet for example:
Say, I have dependency between starting servcies on two nodes. First the the
service on the sever should start, then only service  on the client machines
should start.
For real world example:
Consider, I have Hadoop HA Setup where I want certain services
(ZooKeeper''s) to start before starting the another services on set of
different machines(NameNode''s).
Is this kind of dependencies supported by Puppet? If so can some one explain me
how?

Any help is appreciated.

Thanks,
Ashrith.

Hi, 
Not out of the box. You''d need a combination of puppet and MCollective
to get orchestration.

Cheers
