             Summary: container-executor error should include effective user id
                 Key: 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:

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

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


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.
