I am emiting 'A' value and 'B' value from reducer.

I need to do further calculations also.
which is a better way?
1. Do all remamining computations within reducer , after emiting
or
2.Do remaining computation In driver: read A and B value from part file and
do further computations.

Pls suggest a better way.
