Task $2(4$ marks$)$

Implementation of MapReduce application

Assume, that The Bureau of Meteorology records total yearly rainfall in a number of cities

located in different states. The measurements are recorded in a text file, that contains data

from a period of the last year.

For example, a sample file with the recorded amounts of rainfall could be the following.

The first column contains a name of a state, the second column contains a name of a city

in a state and the third column contains the total rainfall depth per year measured in mm$.$

Queensland Gold Coast $25$

Victoria Melbourne $125$

Victoria Geelong $90$

Victoria Wodonga $10$

NSW Lismore $900$

Queensland Brisbane $50$

South Australia Adelaide $300$

Western Australia Perth $200$

Western Australia Albany $200$

Western Australia Broome $10$

Your task is to implement a MapReduce application, that finds the total rainfall in each

state, the largest rainfall in one location in each state and the smallest rainfall in one

location in each state.

For example, your application should generate the following outputs when processing the

data listed above.

Queensland $755025$

Victoria $22512510$

NSW $900900900$

South Australia $300300300$

Western Australia $41020010$

An input file with the rainfall measurement must include $10$ lines listed above and it must

contain at least $10$ other measurements. All additional measurements are up to you.

Save your solution in a file solution$2.$java. When ready, compile, create jar file,

and process your application. Display the results created by the application. Next, list your

input file with the rainfall measurements. When finished, Copy and Paste the messages

from a Terminal screen into a file solution$2.$pdf$.$
