Please answer:

The columns "Mapper"and "Reducer" in Problem 2.

The columns "Reducer1" and "Reducer2" as well as the questions under said columns.

Problem 2. Word Count Example) Please design the mapper and reducer for the Word Count problem WordCount problem: Given an input text file, count the frequency of each word in the file. Please design the input and output ckey, value> pairs for the Mapper and Reducer. Mapper Reducer Input Output We get the Word Count.jar" file by using the above design. It only contains Mapper and Reducer. There is no combiner and Partitioner in this program. Please illustrate how the Word Countjar program works on the following dataset. This text file only contains one line. the sound sounds sound it is the right right, right? Suppose we run the Word Count.jar program on this file. Suppose that the space symbol, "","" and "?" are all used for separating the words. The outputs of the Mapper are pairs for the Mapper and Reducer.
