Roman Shaposhnik commented on BIGTOP-316:
-----------------------------------------

Sorry for the noise, but I can't seem to make flexible renames work with Puppet. I need to 'phone a friend' at this point ;-)

Here's what I wanted to have:

class hadoop-zookeeper {
   $client_name = "zookeeper"

  define client {
    package { $client_name:
      ensure => latest,
    }
  }
....

that does NOT really work in puppet since apparently referencing variables defined in the class works ONLY if the class itself has been included like this:

include hadoop-zookeeper

Obviously, we can't include ourselves, but we can include a class that is defined inside of us. Which bring me to the following ugly code:

class hadoop-zookeeper {
  class zookeeper {
    $client_name
  }

  define client {
    include zookeeper
    package { $zookeeper::client_name:
      ensure => latest,
    }
  }

Any suggestions on how to solve it better?
