   Thanks. Seems like this failure is because we creates a hash computation for 
all input columns. If there are any NullType in the input, those column types 
will be converted to UNKNOWN Type in Velox, but Velox doesn't support hash 
computing on UNKNOWN types. I would suggest we keep this check, meanwhile drop 
the NullType input columns in the hash computation as the null values doesn't 
affect the hash computation (`hash(x)` and `hash(x, null)` produce the same 
result). Then we can avoid fallback for NullTypes.
