[jira] [Created] (YARN-7363) ContainerLocalizer don't have a valid log4j config in case of Linux container executor

Yufei Gu created YARN-7363:
------------------------------

             Summary: ContainerLocalizer don't have a valid log4j config in case of Linux container executor
                 Key: YARN-7363
                 URL: https://issues.apache.org/jira/browse/YARN-7363
             Project: Hadoop YARN
          Issue Type: Bug
          Components: nodemanager
    Affects Versions: 3.1.0
            Reporter: Yufei Gu
            Assignee: Yufei Gu


In case of Linux container executor, ContainerLocalizer run as a separated process. It doesn't access a valid log4j.properties when the application user is not in the "hadoop" group. The log4j.properties of node manager is in its classpath, but it isn't readable by users not in hadoop group due to the security concern. In that case, ContainerLocalizer doesn't have a valid log4j configuration, and normally no log output.
