Jesus Camacho Rodriguez commented on HIVE-13269:
------------------------------------------------
[~ashutoshc], got it... I need to go through q file changes then, as there are
some tests that will need to be modified: they were written without taking this
into account, and now a filter expression might be removed and the feature they
are supposed to test would be untested...
I could do that, or maybe I could set the flag to true only for
TestPerfCliDriver, what do you think? I think that could give us enough
coverage.
