Program Plan Intro
Hadoop Distributed File System (HDFS):
- Hadoop Distributed File System (HDFS) is the primary data storage systems usually used by the Hadoop applications.
- It was developed as an infrastructure for the Apache Nutch web search engine project and now it is an Apache Hadoop subproject.
- It includes a NameNode and DataNode architecture to implement a distributed file system that is capable of providing high-performance access to data across Hadoop clusters.
MapReduce:
- MapReduce is the processing layer of Hadoop.
- It is an open source application
programming interface that is designed to process large volumes of data in parallel. - The MapReduce framework had two main functions, Map and Reduce.
- The function of the term Map is to take a job and divide into small units of work and the function of the term Reduce is to collect the output generated from different nodes and then integrating them into a single result set.

Question3: (30 MARKS) Passenger Rail Agency for South Africa Train Scheduling System Problem Statement Design and implement a train scheduling system for Prasa railway network. The system should handle the following functionalities: 1. Scheduling trains: Allow the addition of train schedules, ensuring that no two trains use the same platform at the same time at any station. 2. Dynamic updates: Enable adding new train schedules and canceling existing ones. 3. Real-time simulation: Use multithreading to simulate the operation of trains (e.g., arriving, departing). 4. Data management: Use ArrayList to manage train schedules and platform assignments. Requirements 1. Add Train Schedule, Cancel Scheduled Train, View Train Schedules and Platform Management 2. Concurrency Handling with Multithreading i.e Use threads to simulate train operations,…

Question3:
Passenger Rail Agency for South Africa Train Scheduling System
Problem Statement
(30 MARKS)
Design and implement a train scheduling system for Prasa railway network. The system should
handle the following functionalities:
1. Scheduling trains: Allow the addition of train schedules, ensuring that no two trains use the
same platform at the same time at any station.
2. Dynamic updates: Enable adding new train schedules and canceling existing ones.
3. Real-time simulation: Use multithreading to simulate the operation of trains (e.g., arriving,
departing).
4. Data management: Use ArrayList to manage train schedules and platform assignments.
Requirements
1. Add Train Schedule, Cancel Scheduled Train, View Train Schedules and Platform
Management
2. Concurrency Handling with Multithreading i.e Use threads to simulate train operations,
Each train runs as a separate thread, simulating its arrival, departure, and travel status.
3. Use ArrayList to manage train schedules for each…

The JS file should the completion of the task, and all necessary testing, so that just loading the file will complete the task with enough different inputs to ensure it works. Even Numbers [3 marks] Create a function that determines if a provided number is even. Define an array of numbers, then on the array use the appropriate array iterator to determine if the array contains only even numbers using the function you defined. Output the results, and test with several arrays. Long Names [3 marks] Define an array of names. Use an iterator to retrieve a new array containing only the names longer then 12 characters. Your iterator should be passed an anonymous arrow function.
