Big Data (H/M) Assessed Exercise Task Sheet
2024/25 – Individual – v1 07/02/25
Summary
The goal of this exercise is to familiarize yourselves with the design, implementation and 
performance testing of Big Data analysis tasks using Apache Spark. You will be required to design 
and implement a single reasonably complex Spark application. You will then test the running of this 
application on a large dataset. You will be evaluated based on code functionality (does it produce 
the expected outcome), code quality (is it well designed and follows good software engineering 
practices) and efficiency (how fast is it and does it use resources efficiently). We provide you with an 
initial project template similar to the tutorials that you have been using in the labs. This will contain 
some classes that you can use in your solution (so you don’t need to implement them yourself). 
Task Description
You are to develop a financial recommendation platform that can find profitable financial assets and 
display them as a top-5 ranking for an investor, given pricing information and asset fundamental 
data. This is a batch analytics task to be implemented in Apache Spark as a pipeline of data 
transformations and actions. You will be provided a dataset that contains both pricing data and asset 
metadata up-to a set date, where this is the date that you are going to produce recommendations
for, using information on and before that date. The pipeline you need to implement will involve a 
series of stages:

  1. First, the pricing data and asset metadata needs to be loaded in as Resilient Distributed Datasets 
    (RDDs), this is provided for you in the project template.
  2. Second, you will need to transform the daily pricing data into a series of financial ‘Technical 
    Indicators’ that numerically describe how well an asset performed in the past. Classes for 
    calculating these are provided, but you will need to work out how to integrate these into your 
    pipeline of Spark transformations.
  3. Third, after you have calculated these technical indicators, you will need to use them to filter 
    the assets. You should filter out any assets that have a Volatility score greater than or equal to
  4. Fourth, you will need to further use the provided asset metadata to further filter the asset set to 
    remove assets with a Price-to-Earnings Ratio greater than or equal to 25.
  5. Finally, you need to rank the remaining assets for the investor based on asset Returns (Return 
    on Investment) over the most recent 5 days, returning the top 5 assets.
    What you need to collect at the driver program is an AssetRanking class, which contains an array of 5 
    Asset objects (i.e. the final ranking), both these classes are provided in the template. All computation 
    should be performed in a distributed manner using Spark transformations and actions. You may 
    need to collect intermediate data at the driver program between stages of your pipeline, but this 
    should only be a small number of records (under 5k), and you should not need to further process the 
    data at the driver.
    For this exercise, you should implement your transformation functions as Java classes following 
    object-orientated design代写Big Data (H/M) Assessed Exercise  principles, as illustrated in the tutorials. You can use both the Java core API 
    (those based on JavaRDD) and the Java SQL API (those based on Dataset), but you should avoid
    significant use of lambda expressions (as they make your code less interpretable). You should 
    comment the logic for your code in English; have a look at the tutorial code bases for what this might 
    look like.
    Template Classes
    You will be provided with a Java template project 
    like the tutorials. The template project provides 
    implementations of the following code to help you:
    • AssessedExercise: This is the main class, 
    you should call all of your transformations 
    and actions within the rankInvestments
    function of this class.
    • Asset: This class represents a single asset, 
    it is used by AssetRanking, which is the 
    object your program is to return.
    • AssetFeatures: This class holds the 
    returns, volatility and p/e ratio for an 
    asset. This class is used by Asset.
    • AssetMetadata: This object contains 
    descriptive metadata about an asset. You 
    will need the name, industry, sector and 
    price-to-earnings ratio from this in your 
    solution.
    • AssetRanking: An array of Asset, your 
    solution should return one of these with 5 
    assets.
    • StockPrice: This class represents the price 
    data for an asset on a particular day. You 
    need the closing price from these to 
    calculate technical indicators.
    • Returns: This is a class for calculating 
    Return on Investment. The calculate 
    function takes in a number of days to 
    calculate over and a list of close prices 
    sorted by time. numDays should be 5 in 
    your solution.
    • Volatility: This is a class for calculating asset volatility over a period of time. It takes in a list 
    of close prices sorted by time. For your solution you need to provide it the close prices for 
    the prior year, which is 251 days (we only count trading days since markets are not open on 
    weekends).
    • NullPriceFilter: This is a simple filtering class that is run on price loading to remove days 
    where close prices are missing.
    • PriceReaderMap: A simple map that is used to convert from a Spark SQL Row to a 
    StockPrice.
    • AssetMetadataPairing: This is a Spark SQL Row map that converts the raw asset metadata 
    to a Tuple2<String, AssetMetadata> object. The string in this case is the stock ticker/symbol 
    for the asset.
    • MathUtils: This is a utility class that includes some useful math operations. You don’t need 
    to directly use this, it is used by the Returns and Volatility classes.
    • TimeUtil: This is a custom utility class I wrote to make parsing dates easier. In the above 
    requirements, you will note that for calculating returns and volatility you will need to filter 
    the input pricing data to a window of time, but the StockPrice object reports the date in the 
    form of <year,month,day> fields. This class allows you to convert from <year,month,day> to 
    a Java Instant object, which allows for easier time-based operations.
    IDE Setup
    Your integrated development environment (e.g. Eclipse or IntelliJ) should be the same as for the 
    tutorials. However, as this is using the latest version of Apache Spark (4.0.0-preview2) you will need 
    Java JDK 21.0.2, which you can download from jdk.java.net/archive/
    Dataset
    The dataset that you will be using for this exercise is a collection of financial assets from the US stock 
    market spanning the period of 1999 to mid-2020. This is split over two data files:
    • all_prices-noHead.csv: This file contains daily pricing data for around 15,700 financial assets 
    over multiple years. The file contains 24,197,442 price points, and is around 2.4GB in size.
    • stock_data.json: This is a json file that contains metadata collected about various financial 
    assets, such as their name, industry and price-to-earnings ratio. Not all fields are available 
    for all assets. If you need a field for your solution and an asset is missing that field you 
    should filter that asset out.
    When and What to hand in
    The deadline for submission is March 3rd by 4:30pm. You should submit via Moodle:
    • A copy of your code-base as a single zip file. You should only include the ‘src’ directory in your 
    submission.
    How this exercise will be marked
    Following timely submission on Moodle, the exercise will be given a numerical mark between 0 (no 
    submission) and 25 (perfect in every way). The numerical marks will then be converted to a band (A5, 
    A4, etc.). The marking scheme is as follows:
    • 5 marks are awarded for producing the correct output through computation
    • 5 marks are awarded for computational efficiency (benchmarked against my solution)
    • The remaining 15 marks are awarded for the implementation quality
    o 10 marks are awarded for correct implementation of the classes
    o 2 marks are awarded for code documentation (comments).
    o 3 marks are awarded for design that will make yoursolution scale well with more data
    Frequently Asked Questions…
    • Is my solution fast enough? This is a difficult question to answer, as I have a solution that I 
    have implemented, but how that compares to your implementation is impossible to say 
    without running a test on like-for-like hardware. What I can say is that my solution 
    completed in 31 seconds running on an I7-12700, where data was reading from an SSD and 
    the number of threads that the executor was provided with was four (local[4])
    • What are you looking for in terms of efficiency?: We are looking at the statistics from the
    Spark executor dashboard, here is mine for reference:
    • How do I know if I got the right answer? The short answer is you don’t, and I can’t give you 
    the full output, as that is marked, however I can say that the rank one asset my solution
    produces is TOP Ships Inc (TOPS).
    • Can I use <library/programming language X>: No, you have to write in Java to enable fair 
    marking of the exercise.
    • Can I use an AI assistant to help?: Also no, see 
    www.gla.ac.uk/myglasgow/s…
    • Can I ask for help in the labs?: Yes! That is what we are there for, we can’t tell you the 
    solution, but we can provide hints and guidance.
