Chris Nauroth created HADOOP-9488:
-------------------------------------
Summary: FileUtil#createJarWithClassPath only substitutes
environment variables from current process environment/does not support
overriding when launching new process
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.
