> 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());
> }
> {code}
> However, {{getApplicationAttempt}} doesn't return null but throws
> ApplicationAttemptNotFoundException:
> {code}
> if (entity == null) {
> throw new ApplicationAttemptNotFoundException(
> "The entity for application attempt " + appAttemptId +
> " doesn't exist in the timeline store");
> } else {
> return convertToApplicationAttemptReport(entity);
> }
> {code}
> They code isn't coupled well.
