Teddy Choi updated HIVE-15939:
------------------------------
Attachment: HIVE-15939.1.patch
I modified UDFToBoolean to recognize 'true' and 'false' without case
sensitivity. I also created vectorized UDFs.
> Make cast expressions comply more to sql2011

> in HIVE-6590 Jason have uncovered the fact that UDFToBoolean treats all
> non-empty strings as true.
> It would be great to have the cast expressions closer to the standard...at
> least when there is an expected behaviour from the user;
> like {{cast('false' as boolean)}} should be true.
