Description

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

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

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

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.
