> 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
