Change subject: WIP IMPALA-11718: Improve support for Hive Generic UDFs
......................................................................


Patch Set 6:

(3 comments)

This patch looks pretty good to me! Is it possible to add tests on Hive's 
builtin GenericUDFs, e.g. mask(), corr()? The later one is a GenericUDAF.

PS6, Line 22: In this case initialize() will be called during
            :   analyses of the query with the expected argument types.
Do we have tests on analysis errors in this step?

It's run in the above test. Any reason to run it again here?
