> When acls are enabled on the job tracker using the property mapred.acls.enabled, and
a job is submitted to a queue name that does not exist in mapred.queue.names property, the
following exception is thrown:
> org.apache.hadoop.security.AccessControlException: org.apache.hadoop.security.AccessControlException:
User user-name cannot perform operation SUBMIT_JOB on queue queue-name

> The message makes it appear like the queue exists, but the user does not have access
to it, where the actual problem is that the queue does not exist at all.
