puppetdb_query missing from agent

[chengkai liang]

Hi all,

I had this strange thing regarding to puppetdb_query. I am trying to experence PQL.What I do was to create a simple test module that has these content,

class test {

  $debian_nodes_query = 'nodes[certname]{facts{name = "operatingsystem" and value = "Debian"}}'

  $debian_nodes = puppetdb_query($debian_nodes_query).map |$value| { $value["certname"] }

  notify {"Debian nodes":

      message => "Your debian nodes are ${join($debian_nodes, ', ')}",

  }

$last_node_query = "nodes[certname] { certname ~ 'hadoop.*worker-.*' order by certname}"

# $last_node_query = "certname in nodes[certname] { facts[certname] { name = 'icebrg_hadoop_group' and value = 'shakedown_test' } group by certname order by certname }"

$latest_node = puppetdb_query($last_node_query)

Notify {"hello PQL":

    message => "My last report was from $latest_node.",

}

}

While the above module was able to successfully execute from puppet master. It failed on one of my agents with the following complain,

Error: Evaluation Error: Unknown function: 'puppetdb_query'. (file: /tmp/test/manifests/init.pp, line: 3, column: 19) on node xxx

I found on the puppet master side, these components exists

/opt/puppetlabs/puppet/cache/lib/puppet/provider/puppetdb_conn_validator/puppet_https.rb

/opt/puppetlabs/puppet/cache/lib/puppet/type/puppetdb_conn_validator.rb

/opt/puppetlabs/puppet/cache/lib/puppet/util/puppetdb_validator.rb

/opt/puppetlabs/puppet/cache/lib/puppetdb/astnode.rb

/opt/puppetlabs/puppet/cache/lib/puppetdb/connection.rb

/opt/puppetlabs/puppet/cache/lib/puppetdb/grammar.racc

/opt/puppetlabs/puppet/cache/lib/puppetdb/lexer.rb

/opt/puppetlabs/puppet/cache/lib/puppetdb/lexer.rex

/opt/puppetlabs/puppet/cache/lib/puppetdb/parser.rb

/opt/puppetlabs/puppet/cache/lib/puppetdb/parser_helper.rb

But they are not exist on the agent side. Anyone can help me on this?

Thanks,
