Description

Overview

Getting a difficult to diagnose error. No idea what’s failing in the parsing of the manifest since I don’t have a line number or manifest file to reference.

Error message:

undefined method `<<' for {}:Hash on node rhel6_64.vagrant.internal

Steps to reproduce

I’ve attached a small vagrant project with everything required to reproduce this error. The base box will automatically be downloaded if you run “vagrant up” after unpacking the tarball it should just fail.

I found the issue.

Using the –> relationship syntax should work between this user and group resource, but does not.

The following puppet code works:

group { 'mockbuild':
  ensure => present,
  gid    => $gid_real,
  before => File[$home],
}
# ->
user { 'mockbuild':
  ensure   => present,
  uid      => $uid_real,
  gid      => $gid_real,
  comment  => 'Mock Build',
  shell    => '/bin/bash',
  home     => $home,
  password => '!!',
  require  => Group['mockbuild'],
}

The following code reproduces the error. Note, the only difference is the relationship declaration.

group { 'mockbuild':
  ensure => present,
  gid    => $gid_real,
  before => File[$home],
}
->
user { 'mockbuild':
  ensure   => present,
  uid      => $uid_real,
  gid      => $gid_real,
  comment  => 'Mock Build',
  shell    => '/bin/bash',
  home     => $home,
  password => '!!',
  require  => Group['mockbuild'],
}

Is it worth renaming the ticket, to make it a little clearer of the issue?

I have also seemed to run into this bug.

File[cdh3_config] –> Package[jobtracker]

works but

File[cdh3_config] ~> Service[jobtracker]

does not.

I’ve also come across this error trying to do a complicated relationship.

Package <| |> –> File <| |> ~> Service <| |> –> Exec[“joinNetwork”]

Where Package, File, and Service deal with several objects each. Removing the subscription between File and Service does not resolve the error. Puppet parses the manifest without error.

Note that bug #7422 is likely the same issue.
