I have a follow-up question -- Bikas mentioned that the Tez App Master submits one DAG at a time -- Now, for a Query engine like Hive, where there would be multiple requests, how is this handled? Are we creating multiple App Masters that round robins between them? Even then, when large number of requests are submitted to the Hive server, if the App master can submit only one DAG at a time, we would have situations where there would be many outstanding requests. Is there a way we can make the App Master multi-threaded?
