------------------------------------------------------------------
The getSortJob looks good. The getQuantileJob has similar code where the result
type of the project operator is set to DataType.BYTEARRAY instead of the type
of the projection operator. Maybe this code has to change to reflect the logic
in the getSortJob method.
