Description

Poking around in my vagrant-puppet deployer, im finding that I dont have a NM running.

So I have to run:

 service hadoop-yarn-nodemanager start

EVEN if i specify:

components = yarn,hadoop 

So either:

1) The nodemanager service should be a valid component that we can turn on or off in the config/site.csv file or

2) The puppet recipes should be smart enough to start a nodemanager for us (i.e. if yarn is a component than always start and run nodemanager).

I think (1) is better since in some deployments we may not want a NM on every node.

Forgive me if this "bug" report is really not a bug at all, maybe just my ignorance on the way we are supposed to run NMs?
