Edward Capriolo commented on HIVE-5538:
---------------------------------------

I do not like the idea of turning on vectorize by default until we have a way to test both
code paths, and am -1 until this is addressed.

>   Vectorization should be turned on by default, so that users don't have to specifically
enable vectorization. 
>   Vectorization code validates and ensures that a query falls back to row mode if it
is not supported on vectorized code path.
