--------------------------------------------------------------

I mean that the very first, but crucial problem of current implementation of FPM algorithm is the explosion of intermediate data when generating frequent patterns.
Above explosion makes FPM not available in many cases even we use very small input.
That problem comes from the shortage of intermediate buffer of MapReduce, but as we consider the FPM in the algorithm-level, so we should find the another alternatives either to avoid or handle that problem I mentioned.
