> In the case when log aggregation is enabled, if a user submits MapReduce job and runs
$ yarn logs -applicationId <app ID> while the YARN application is running, the command
will return no message and return user back to shell. It is nice to tell the user that log
aggregation is in progress.
> {code}
> -bash-4.1$ /usr/bin/yarn logs -applicationId application_1377900193583_0002
> -bash-4.1$
> {code}
> At the same time, if invalid application ID is given, YARN CLI should say that the application
ID is incorrect rather than throwing NoSuchElementException.
> {code}
> $ /usr/bin/yarn logs -applicationId application_00000
> Exception in thread "main" java.util.NoSuchElementException
