If you have multiple reducers you are doing it in parallel while in the
driver it is surely single threaded so my bet would be on the reducers.

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.
