Newton -> Queens FFU upgrade: fast_forward_upgrade_playbook fails with Error: Evaluation Error: Error while evaluating a Function Call, Could not find data item nova::rabbit_password in any Hiera data file and no default supplied at /root/nova-api_upgrade_manifest.pp:6:18 on node controller-0.localdomain

Checking the overcloud controller it looks that the hierarchy section in /etc/puppet/hiera.yaml doesn't point to any files:

[root@controller-0 ~]# cat /etc/puppet/hiera.yaml
---
:backends:
  - json
  - yaml
:json:
  :datadir: /etc/puppet/hieradata/
:yaml:
  :datadir: /etc/puppet/hieradata
:hierarchy:
