Gunther Hagleitner commented on HIVE-13342:
-------------------------------------------
I don't think we need to log each time we look at an operator or vertex. At
least not on info level. That will be too noisy. But we should add logging each
place in the code where we decide LLAP isn't an option. And then with a reason
(which I think is missing in this patch still).
> Improve logging in llap decider and throw exception in case llap mode is all
> but we cannot run in llap.

> Currently we do not log our decisions with respect to llap. Are we running
> everything in llap mode or only parts of the plan. We need more logging.
> Also, if llap mode is all but for some reason, we cannot run the work in llap
> mode, fail and throw an exception advise the user to change the mode to auto.
