You should be able to declare parameterized classes via crete_resources().

If you use a hash like:

  testfoo::class2: {}
    require: Class['testfoo::class2']

and code like:

  $classes = hiera_hash('classes')
  create_resources('class', $classes)

you wind up with an error like:

Invalid relationship: Class[testfoo::class1] { require => Class[testfoo::class2] }, because Class[testfoo::class2] doesn't seem to be in the catalog.

However, specifying the hash in the manifest and using puppet apply works:

# cat ~/test.pp
class test1 { notify { 'test1': } }
class test2 { notify { 'test2': } }
$classhash = {
  'test1' => { 'require' => "Class[test2]" },
  'test2' => { }
create_resources('class', $classhash)
# puppet apply test.pp

There must be something that makes the hash produced by hiera_hash different from the manually created hash. What happens if the yaml file has this:

    require: "Class[testfoo::class2]"

instead of this:

    require: Class['testfoo::class2']

It should also be easy to assert if a lookup via hiera_hash has the exact same content as the manually created hash.

It looks like it works if hiera data is given the correct way. please reopen if that is not the case.
