             Summary: Contaniner-executor may fail with wrong information
                 Key: YARN-2898
                 URL: https://issues.apache.org/jira/browse/YARN-2898
             Project: Hadoop YARN
          Issue Type: Bug
            Reporter: Wei Yan
            Assignee: Wei Yan
            Priority: Minor

*Settings*: YARN cluster using LinuxContainerExecutor, and the "banned.users" 
is left empty in the container-executor.cfg. The default banned list is 
\{"mapred", "hdfs", "bin"\}.

*Problem*: let user "mapred" submit a job, it will fail with "ExitCodeException 
exitCode=139", which is segment fault. This is incorrect, and the correct 
information should be "Requested user mapred is banned".
