> When generating app report in ApplicationHistoryManagerOnTimelineStore, it 
> checks if appAttempt == null.
> {code}
>         ApplicationAttemptReport appAttempt = 
> getApplicationAttempt(app.appReport.getCurrentApplicationAttemptId());
>         if (appAttempt != null) {
>           app.appReport.setHost(appAttempt.getHost());
>           app.appReport.setRpcPort(appAttempt.getRpcPort());
>           app.appReport.setTrackingUrl(appAttempt.getTrackingUrl());
>           
> app.appReport.setOriginalTrackingUrl(appAttempt.getOriginalTrackingUrl());

> However, {{getApplicationAttempt}} doesn't return null but throws

> They code isn't coupled well.
