GH-254: XConfiguration should give precedence to variables over sys-props in 
${} expressions
--------------------------------------------------------------------------------------------

                 Key: OOZIE-206
                 URL: https://issues.apache.org/jira/browse/OOZIE-206
             Project: Oozie
          Issue Type: Bug
            Reporter: Hadoop QA


Currently if a config file as a property

  user.name=foo
  foo.output=/user/${user.name}/output

If *XConfiguration* is used from a process owned by the user 'oozie' then 
*foo.output* gets resolved to */user/oozie/output*

For how Oozie uses Configurations it should resolve to */user/foo/output*

I'll raise an issue in Hadoop to change this, but I'm fearing that they'll 
claim that a change to current behavior will break existing applications.
