TCM Constitution Analysis Method Based on Parallel FP-Growth Algorithm in Hadoop Framework

Algorithm 1

Generating local frequent item sets.

	Input: (line offset, T)
	Output: (Ii, Ni)
	map: for each item I in T ()
	output (I, 1)
	reduce: count = 0
	while (values.hasNext()) count = count+1
	output (I, count)
