"yarn logs" prints an error message like the following:
> {noformat}
> [andrew.wang@a2402 ~]$ yarn logs -applicationId application_1394482121761_0010
> 14/03/10 16:05:10 INFO client.RMProxy: Connecting to ResourceManager at a2402.halxg.cloudera.com/
> Logs not available at /tmp/logs/andrew.wang/logs/application_1394482121761_0010
> Log aggregation has not completed or is not enabled.
> {noformat}
> It'd be nicer if it said "Permission denied" or "AccessControlException" or something
like that instead, since that's the real issue.
