> If the application history service has been enabled and RM has forgotten anout an application,
try and fetch the app report form the AHS.
> On larger clusters, the RM can forget about the applications in about 30 minutes. The
proxy url generated during the job submission will try to fetch the app report from the RM
and will fail to get anything from there. If the app is not found in the RM, we will need
to get the application report from the Application History Server  (if it is enabled) to see
if we can get any information on that application before throwing an exception.
