Description

If hiera is configured for multiple backend, if the first backend fail to find data it will result in immediate failure even if the second backend supplies data. This doesn’t affect hiera function, just hiera_array hiera_hash (which is almost identical except how the data is handled.

:hierarchy: - %{certname}

These all go together, the hiera-puppet and hiera-json pull requests bring those into line with the changes in the hiera pull request. This takes the opposite approach of the previous pull request, moving to using nil consistently instead of empty hashes and arrays consistently.
