Thejas M Nair commented on HIVE-10122:
--------------------------------------
yeah, it would be really good to have unit tests for these. That would have
detected this regression in the first place.
If logs need to be looked at, that is also possible. See my changes to TestHive
in HIVE-10214, its easy to capture log output from specific classes.
