--------------------------------------

             Summary: container-executor error should include effective user id
                 Key: YARN-4065
                 URL: https://issues.apache.org/jira/browse/YARN-4065
             Project: Hadoop YARN
          Issue Type: Improvement
          Components: yarn
            Reporter: Casey Brotherton
            Priority: Trivial


When container-executor fails to access it's config file, the following message will be thrown:

{code}
org.apache.hadoop.yarn.server.nodemanager.LinuxContainerExecutor: Exit code from container executor initialization is : 24
ExitCodeException exitCode=24: Invalid conf file provided : /etc/hadoop/conf/container-executor.cfg
{code}

The real problem may be a change in the container-executor not running as set uid root.

From:
https://hadoop.apache.org/docs/r2.6.0/hadoop-yarn/hadoop-yarn-site/SecureContainer.html

{quote}
The container-executor program must be owned by root and have the permission set ---sr-s---.

The error message could be improved by printing out the effective user id with the error message, and possibly the executable trying to access the config file.
