Kengo Seki updated HADOOP-9642: ------------------------------- Attachment: HADOOP-9642.001.patch Attaching a preliminary patch. Default values are not supported yet. > Configuration to resolve environment variables via ${env.VARIABLE} references > ----------------------------------------------------------------------------- > > Key: HADOOP-9642 > URL: https://issues.apache.org/jira/browse/HADOOP-9642 > Project: Hadoop Common > Issue Type: Improvement > Components: conf, scripts > Affects Versions: 3.0.0, 2.1.0-beta > Reporter: Steve Loughran > Priority: Minor > Attachments: HADOOP-9642.001.patch > > > We should be able to get env variables from Configuration files, rather than > just system properties. I propose using the traditional {{env}} prefix > {{${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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
