Summary: Handle the user name correctly when submit application
and use user name as default queue name.
Key: YARN-3395
URL: https://issues.apache.org/jira/browse/YARN-3395
Project: Hadoop YARN
Issue Type: Bug
Components: scheduler

Handle the user name correctly when submit application and use user name as
default queue name.
We should reject the application with an empty or whitespace only user name.
because it doesn't make sense to have an empty or whitespace only user name.
We should remove the trailing and leading whitespace of the user name when we
use user name as default queue name, otherwise it will be rejected by
InvalidQueueNameException from QueueManager. I think this change make sense,
because it will be compatible with queue name convention and also we already
did similar thing for '.' in user name.
