CDS504 - Enabling Technologies & Infrastructures for Big Data

Semester 2, Academic Year 2023/2024

Assignment 1

Objective Analyze income inequality or rich-poor disparity in a country, using Hadoop MapReduce.

Tasks

i)    Identify a problem/issue/aspect related to income inequality or rich-poor disparity which can be solved/processed using MapReduce.

ii)   Find a suitable open/free dataset related to income inequality or rich-poor disparity for Malaysia (or your own country). (E.g. data.gov.my, dosm.gov.my, kaggle.com, data.world, data.gov, data.worldbank.org, etc.)

iii)  Extract and reformat the data you’re interested in, if needed.

iv)   Show how the various stages of MapReduce (i.e. splitter, mapper, shuffler/sorter, reducer) will process your data. The reducer should implement at least 2 different functions (i.e. total, average, median, maximum, minimum, standard deviation, etc.).

v)    Show how new/interesting results (which originally did not exist in the dataset) could be obtained after processing by MapReduce.

You are not required/expected to install Hadoop MapReduce or write MapReduce program code for your solution.  Just simulate (on paper, via diagrams & description) how MapReduce will process the dataset to produce interesting results.

Hint/Suggestion

Use WordCount example as basis, but develop a new/different solution for your objective, using the selected dataset.

Report

Prepare a written report which include the following:

.     Problem statement (i.e. what is the issue), motivation (i.e. why is the issue important, why MapReduce is suitable, etc.) and the goal of your work (i.e. hypothesis, expected end-result, how it will be useful, etc.).

.     Description of the selected dataset.

.     Data pre-processing and reformatting, if any.

.     How the mapper and reducer process the data.  Show the various stages, with their intermediate results.

.     Description and discussion on the final results obtained.

.     Reflection (i.e. lessons learned, experience developing solution for MapReduce, challenges faced, etc.).

.     References

.     Appendix – Sample of dataset used (original and extracted/reformatted).

Online Submission

Upload the report (in PDF format) to eLearning portal.  Only one submission per group is required.

Viva

No presentation required.
