Upgraded to Puppet 3.7.3 (Puppet Enterprise 3.7.1), had a working environment in PE3.2.3. issue: deeper merge of hiera_hash no longer works.


  - yaml
  :datadir: /etc/puppet/hieradata/
:merge_behavior: deeper
  - "nodes/%{fqdn}"
  - "environment/%{environment}"
  - common


      - mcrypt


      - cli

inside my puppet module:

  # Hiera Data Lookup
  $web_values = hiera_hash('web', false)
  notify {"web_values: ${web_values}":}

output puppet agent:

  {"php"=> {"modules"=>["cli"]}}

output hiera commandline lookup:

  {"php"=> {"modules"=>["mcrypt", "cli"]}}

So a commandline lookup with option --hash gives me the expected result. Inside a Puppet run it fails. Any help is appreciated. I have the deep_merge gem installed. Hiera version: 1.3.4

The JRuby processes run by the Puppet Server use a separate set of gems. Have you also installed deep_merge via `/opt/puppet/bin/puppetserver gem install`?

That did the trick. Deeper merge is working again. Thanks! How can I flag your comment as answer?

The deep_merge gem needs to be installed via:

/opt/puppet/bin/puppetserver gem install

The JVM-based Puppet Server (included in PE since 3.7) uses JRuby to run the Puppet Master process. Because of the JRuby runtime, the Puppet Server has to maintain a separate set of gems than what is used by CRuby tools such as the Puppet Agent and the Hiera command line. Note that JRuby will not be able to install gems using compiled C code; such as non-JDBC database drivers.
