Brock Noland commented on HIVE-5423:
------------------------------------

I am very much in favor of using unit tests over qfile tests as I think it's 
much easier to target a specific piece of code, faster, and it's easier to 
identify the issue at hand.  It looks like we'd be able to test multiple rows 
which is an important requirement.

The only issue I can see is it's fair amount of work. I'd love to help but I've 
got the maven and website projects on my plate present so I am not sure I will 
able to until those projects are nearing completion.

Another, minor consideration is that if we were able to do this on a mass scale 
we'd either want to implement HIVE-4907 or be on maven so that we can run 
multiple JUnit tests in a single call to ant test otherwise HiveQA would slow 
down considerably since it can only run a single unit test per call to ant 
test. If we had 50-100 more unit tests before we mavenized I think we'd want to 
implement HIVE-4907.
