Mark Wagner commented on HIVE-5423:
-----------------------------------
I think this would be a big improvement and would likely improve the coverage
of our UDFs. The only disadvantage over qtests I see is that it is a bit more
involved. If we adopt some conventions about the input, such as "all columns
are fed to the udf as parameters in the same order", then all the operator
pipeline construction logic can be extracted and writing tests for a new UDF
will be more accessible to a new dev.
