> Following issues are causing many queries to fail to vectorize:
> 1) NPE because row resolver is null.
> 2) VectorUDFAdapter doesn't handle decimal.
> 3) Decimal cast to boolean, timestamp, string fail because classes are not annotated appropriately.
> 4) Decimal modulo fails to vectorize because GenericUDFOPMod is not annotated.
