Gopal V commented on HIVE-13957:
--------------------------------
Would it be better to convert the implicit conversion (as done in GenericUDF)
into an explicit one if the type conversion is legal?
Similar type issues exist for concat() for instance, where the UDF internally
type-casts all args to String, but the actual plan doesn't.
> vectorized IN is inconsistent with non-vectorized (at least for decimal in
> (string))

> The cast is applied to the column in regular IN, but vectorized IN applies it
> to the IN() list
