Vinod Kumar Vavilapalli commented on YARN-873:
----------------------------------------------
bq. Would be good to make the behavior consistent. Its ok to throw the same
exception in the server for both cases.
+1, let's not add null-checks for clients. Similar to FileNotFoundException, we
should have an ApplicationNotFoundException or a UnknownApplicationException
which clients can cleanly handle. And +1 for making getAppReport()/killApp()
all using the same exception.
> YARNClient.getApplicationReport(unknownAppId) returns a null report
