Jerakia has the concept of a namespace and a key, by default the file lookup datasource will look for key in
<datadir>/<scope>/<namespace>.yaml - in order to retain Hieras way of doing things, which is to lookup
<namespace>::<key> in a file called
<datadir>/<scope>.yaml a plugin hiera has been provided. To enable this in your lookup simply add the directive to the lookup block and the request key and namespace will automatically get re-written on the fly
There is no need to call a method using the hiera plugin. By including it in the lookup, the
autorun method of the plugin will automatically rewrite the lookup.
