> When the ResourceManager kills an application, it leaves the proxy URL
> redirecting to the original tracking URL for the application even though the
> ApplicationMaster is no longer there to service it. It should redirect it
> somewhere more useful, like the RM's web page for the application, where the
> user can find that the application was killed and links to the AM logs.
> In addition, sometimes the AM during teardown from the kill can attempt to
> unregister and provide an updated tracking URL, but unfortunately the RM has
> "forgotten" the AM due to the kill and refuses to process the unregistration.
> Instead it logs:
> {noformat}
> 2013-01-09 17:37:49,671 [IPC Server handler 2 on 8030] ERROR
> org.apache.hadoop.yarn.server.resourcemanager.ApplicationMasterService:
> AppAttemptId doesnt exist in cache appattempt_1357575694478_28614_000001
> {noformat}
> It should go ahead and process the unregistration to update the tracking URL
> since the application offered it.
