Please design the mapper and reducer for the below WordCount problem. WordCount problem: Given an input text file, count the frequency of each word in the file. Please design the input and output pairs for the Mapper and Reducer, use below table for reference. Input Output We get the "WordCount.jar" file by using the above table. It only contains Mapper and Reducer. There is no Combiner and no Partitioner in this program. Mapper Please illustrate how the WordCount.jar program works on the below dataset. This text file only contains one line. Dataset: the sound sounds sound. it is the right right, right? Suppose we run the WordCount.jar program on this file. Suppose that the space symbol, and "?" are all used for separating the words. The outputs of the Mapper are Reducer The outputs of the reducer are Are the results sorted alphabetically? When was it sorted?
