Zoltan Haindrich updated HIVE-15939:
------------------------------------
Attachment: HIVE-15939.6.patch
#6)
* make cast expression align with HIVE-6590 ; accept {{false|off|no|0|}}...
values as false; others as true.
* I'm not sure; but I haven't changed {{CastStringToLong}} which has a very
different mindset currently: {{TRUE/FALSE/T/F}} with case insensitivity to its
respective values; other values are mapped to NULL... this is very different so
I've left it alone..
> 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.
