----------------------------------
Summary: Allow parameter expansion in NM_ADMIN_USER_ENV
Key: YARN-10664
URL: https://issues.apache.org/jira/browse/YARN-10664
Project: Hadoop YARN
Issue Type: Improvement
Components: yarn
Affects Versions: 2.10.1, 3.4.0
Reporter: Jim Brennan
Assignee: Jim Brennan
Currently, {{YarnConfiguration.NM_ADMIN_USER_ENV}} does not do parameter
expansion. That is, you cannot specify an environment variable such as
{code}{{JAVA_HOME}}{code} and have it be expanded to {{$JAVA_HOME}} inside the
container.
We have a need for this in specifying different java gc options for java
processing running inside yarn containers based on which version of java is
being used.
