+ {@link SubmitApplicationResponse} from ResourceManager doesn't guarantee
+ that RM 'remembers' this application beyond failover or restart. If RM
+ failover or RM restart happens before ResourceManager saves the
+ application's state successfully, the subsequent
+ {@link #getApplicationReport(GetApplicationReportRequest)} will throw
+ a {@link ApplicationNotFoundException}. The Clients need to re-submit
+ the application with the same {@link ApplicationSubmissionContext} when
+ it encounters the {@link ApplicationNotFoundException} on the
+ {@link #getApplicationReport(GetApplicationReportRequest)} call.</p>
+
+ <p>During the submission process, it checks whether the application
+ already exists. If the application exists, it will simply return
+ SubmitApplicationResponse</p>
