> Key: HADOOP-9488
> URL: https://issues.apache.org/jira/browse/HADOOP-9488
> Project: Hadoop Common
> Issue Type: Bug
> Components: fs
> Affects Versions: 3.0.0
> Reporter: Chris Nauroth
> Assignee: Chris Nauroth
>
> {{FileUtil#createJarWithClassPath}} always uses {{System#getEnv}} for
> substitution of environment variables in the classpath bundled into the jar
> manifest. YARN launches container processes with a different set of
> environment variables, so the method needs to support providing environment
> variables different from the current process.
