Allen Wittenauer updated HADOOP-9642:
-------------------------------------
Component/s: scripts
> Configuration to resolve environment variables via ${env.VARIABLE} references
> -----------------------------------------------------------------------------
>
> Key: HADOOP-9642
> URL: https://issues.apache.org/jira/browse/HADOOP-9642
> Project: Hadoop Common
> Issue Type: Improvement
> Components: conf, scripts
> Affects Versions: 3.0.0, 2.1.0-beta
> Reporter: Steve Loughran
> Priority: Minor
>
> We should be able to get env variables from Configuration files, rather than
> just system properties. I propose using the traditional {{env}} prefix
> {{${env.PATH}}} to make it immediately clear to people reading a conf file
> that it's an env variable -and to avoid any confusion with system properties
> and existing configuration properties.
