[jira] [Commented] (OOZIE-206) GH-254: XConfiguration should give precedence to variables over sys-props in ${} expressions

["Hadoop QA (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/OOZIE-206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13099888#comment-13099888 ] 

Hadoop QA commented on OOZIE-206:
---------------------------------

tucu00 remarked:
This help with usability and will fix an issue with the examples where ${user.name} is used in job.properties but it is wrongfully interpreted:

oozie.wf.application.path=hdfs://localhost:9000/user/${user.name}/examples/apps/no-op

> 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.
