> When using LCE in a secure setup, if "banned.users" is not set in 
> container-executor.cfg, submit job with user in DEFAULT_BANNED_USERS 
> ("mapred", "hdfs", "bin", 0)  will receive unclear error message.
> for example, if we use hdfs to submit a mr job, we may see the following the 
> yarn app overview page:
> {code}
> appattempt_1391353981633_0003_000002 exited with exitCode: -1000 due to: 
> Application application_1391353981633_0003 initialization failed 
> (exitCode=139) with output: 
> {code}
> while the prefer error message may look like:
> {code}
> appattempt_1391353981633_0003_000002 exited with exitCode: -1000 due to: 
> Application application_1391353981633_0003 initialization failed 
> (exitCode=139) with output: Requested user hdfs is banned 
> {code}
> just a minor bug and I would like to start contributing to hadoop-common with 
> it:)
