Property and Locality Data Analysis

Introduction

This project involves setting up a data engineering pipeline to collect, store, process, and analyze Property and Locality data using Hadoop, Docker, MySQL, Tailscale, and Selenium.

Project Overview

• Objective: Analyze Property and Locality data to derive meaningful insights.
• Scope: Collect data through web scraping, store in HDFS, process using Hadoop, and analyze with MySQL.

Here is a demo video of the Pipeline:

Setup and Environment

Virtual Machines Setup

• Step: Installed Ubuntu on VirtualBox for each VM.
• Action: Configured each VM with necessary packages including Docker and Docker Compose.

Networking with Tailscale

• Step: Installed and configured Tailscale on all VMs.
• Action: Created a secure virtual network to enable communication between VMs.

Docker Swarm Initialization

• Step: Initialized Docker Swarm on the master node and joined worker nodes.
• Action: Used Docker Swarm for container orchestration.

Data Collection

Web Scraping with Selenium

• Step: Installed Selenium and Chrome WebDriver.
• Action: Developed scripts to scrape Property and Locality data from various websites.

Data Storage in HDFS

• Step: cd spark cluster folder to use, A ready to go Big Data cluster (Hadoop + Hadoop Streaming + Spark + PySpark + Jupyter Notebook) with Docker and Docker Swarm! Configured HDFS on the Hadoop cluster provided by Prof. Dr.-Ing. Binh Vu. Check the README.md file in the spark cluster folder to begin with the setup process`
• Action: Stored scraped data in HDFS with appropriate partitioning and replication.

Data Processing

Hadoop Job Development

• Step: Developed and executed Hadoop jobs for data cleaning and transformation.
• Action: Used MapReduce for distributed processing.

Failure Test

• Step: Conducted data read/write operations while intentionally shutting down a worker node.
• Action: Verified system resilience and fault tolerance.

Data Ingestion into MySQL

Database Design

• Step: Created a relational database schema in MySQL.
• Action: Developed scripts to ingest data from HDFS to MySQL.

Business Insights

Query Development

• Step: Developed SQL queries to extract insights from the database.
• Action: Generated graphs and tables to present the results.
