I don't know if it's a bug with the version of Puppet ( 3.7.1 ) or Hiera ( 1.3.4 ) that I'm using, but calling_class doesn't seem to be working properly.

For example, when I set up manifests and hiera similar to what you've got here, and I assign the role 'role::puppetmaster' to a node, Hiera pulls the data from roles/role.yaml, not roles/role::puppetmaster.yaml. It seems like calling_class is the class where the hiera_* call is made, not the subclass.

Did you try module_name ?
I had better luck with it than calling_class
