Puppet recipes: Should they start a NodeManager if yarn is enabled?

      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?
