Step	FPgrowthReducer.class; public void map (LongWritable key, Text value, Context context){
1	Split each row of value by, and store them in the arr array;
2	Create a new LinkedList collection list;
3	Use the for loop to read out the arr array sequentially {
4	If an item ele in the arr array is in the frequent 1 itemset; {
5	Write the ele to the list collection;
6	New LinkedList<List<String>>linked list trans;
7	Create a new String array arr;
8	Assign the array to values divided by \t;
9	Declare and initialize a new LinkedList<String> linked list list;
10	Use the for loop to read out the contents of the arr array in turn;
11	Add each item ele to list;
12	Add list to collection trans; }}
