I want to implement a Fast Fourier Transform algorithm with MapReduce. I know of a recursive-FFT algorithm but I need your guideline in order to implement it using a Map/Reduce approach.
Any suggestions/references?

The basic idea that we can use some theorems to divide problem into subproblems.
In case of Fourier Transfom, problem is standard definition of FT:
After applying Cooley–Tukey FFT algorithm we can split it to two subproblems:
Moving forward with that transfomation, theoretically it could be solved with parallel programming.
