Vikram Dixit K commented on HIVE-13342:
---------------------------------------

[~sershe] I think the test fails because of the usage of a temporary function. I think that is the kind of behavior we want to enforce with this change. I have updated the test accordingly. Let me know if you have any feedback.

> 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.
