Comment 2 for bug 1542307

2016-02-04 23:28:39 +0000 Puppet (err): pick(): must receive at least one non empty value at /etc/puppet/modules/osnailyfacter/modular/openstack-cinder/db.pp:19 on node node-1.test.domain.local

The issue is hiera_hash('mysql_hash',{}) doesn't do a proper deep lookup. We need to get rid of all _hash references sine we have deep hash lookups. I think it's too late to fix this for 8.0, though.
