> Looks like integer types (short, int, etc) fail the conversion due to the 
> leading/trailing spaces and return NULL, while float/double/decimal do not. 
> In fact, Decimal used to also return NULL in previous versions up until 
> HIVE-10799.
> Let's try to make this behavior consistent across all of these types, should 
> be simple enough to strip spaces before passing to number formatter.
