[jira] [Created] (BIGTOP-1654) change some hadoop puppet variables from local to node scope

vishnu gajendran created BIGTOP-1654:
----------------------------------------

             Summary: change some hadoop puppet variables from local to node scope
                 Key: BIGTOP-1654
                 URL: https://issues.apache.org/jira/browse/BIGTOP-1654
             Project: Bigtop
          Issue Type: Bug
          Components: deployment, hadoop
    Affects Versions: 0.8.0
            Reporter: vishnu gajendran
             Fix For: 0.9.0


the purpose of this change is to refactor certain puppet variables in cluster.pp and init.pp scripts. Precisely, I would like to change the configurable parameters like $ha and $auth from "local" to "node" scope. I believe, there is no need to pass in these variables to every module/class as these parameters doesn't change once set. With puppet 3 (static scoping) , this change is mandatory as I currently see these variables ($ha, $auth) referenced in multiple places assuming that it is defined in some outer scope. This will not work with puppet 3.
