> In the patch for YARN-1372, ApplicationImpl on NM should guarantee to clean
> up already completed applications. But it will only remove appId from
> 'app.context.getApplications()' when ApplicaitonImpl received evnet
> 'ApplicationEventType.APPLICATION_LOG_HANDLING_FINISHED' , however NM might
> receive this event for a long time or could not receive.
> * For NonAggregatingLogHandler, it wait for
> YarnConfiguration.NM_LOG_RETAIN_SECONDS which is 3 * 60 * 60 sec by default,
> then it will be scheduled to delete Application logs and send the event.
> * For LogAggregationService, it might fail(e.g. if user does not have HDFS
> write permission), and it will not send the event.
