10. Figure below shows an execution of a practical MapReduce programme called WebVisCounter. The program counts the number of times users connect to or visit a given website using a particular operating system (e.g. Windows or Mac). A single line of a typical web server log file is fed into the MapReduce framework, which is shown in the Line offset column. Here, you are required to demonstrate your understanding of MapReduce execution by working out the outcome of each task/box figure shown below (e.g. MAP1, MAP2, PAR1, PAR2, etc.) where the final outcome should match the expected result at the Output stage.
