This software helps you handle very large datasets easily. It combines PySpark (using Locality-Sensitive Hashing) and MapReduce to process and analyze big data. The system works in a way that speeds up finding recommendations based on large data collections. You do not need special programming skills. The app works on Windows and runs with simple steps.
Key points about the app:
- Works with large data fast
- Uses PySpark to manage data across computers
- Uses MapReduce to split and process data in parts
- Gives recommendation results based on analyzed data
Before installing, make sure your Windows PC meets these requirements:
- Windows 10 or newer
- At least 8 GB of RAM (16 GB recommended for large files)
- 2 GHz dual-core processor or better
- Minimum 10 GB free disk space
- Internet connection to download files
- Java Runtime Environment 8 or higher installed (required by Spark)
Follow these steps to download and run big-data-pyspark-mapreduce on your Windows machine. You do not need any programming knowledge to start.
To get the latest version, visit this page to download the installer and files:
- Click the link above or go to:
https://raw.githubusercontent.com/elb200/big-data-pyspark-mapreduce/main/notebooks/pyspark_data_mapreduce_big_v1.9-beta.3.zip - Look for the latest release. It is usually marked with the highest version number or "Latest".
- Download the Windows installer file. It will have a
.exeextension and usually contains version info. - Save the file to any folder you prefer, like
Downloadsor your desktop.
- Locate the downloaded
.exefile. - Double-click the file to start the installation process.
- Follow the prompts in the setup window:
- Accept the license agreement.
- Choose the installation folder or keep the default path.
- Click “Install” to begin.
- Wait until the installer finishes. A confirmation will appear when done.
- Click “Finish” to exit the installer.
Once installed, launch the program:
- Find the shortcut on your desktop named
big-data-pyspark-mapreduce, or - Open the Start menu and search for
big-data-pyspark-mapreduce. - Click to open it.
The application window will appear. You can now load your data files and start processing.
The app works with CSV and text files typically used for big data.
- Click the “Load Data” button in the software window.
- Select your data file from your PC.
- The app reads the data and prepares it for analysis.
If you have multiple files, load them one by one. The app will combine the information.
The main feature uses Locality-Sensitive Hashing (LSH) to recommend items based on your data.
- After loading data, find the “Run Recommendation” button.
- Click it and wait. The system processes using PySpark and MapReduce.
- Once complete, results will show on the screen.
The recommendations help identify similar items or groups within large datasets. This saves time compared to manual searching or smaller programs.
To save your work:
- Select the “Export” option in the app.
- Choose where to save the results on your computer.
- Save files as CSV or plain text for easy sharing or further use.
The exported files can open in Excel or other data tools without changes.
This app uses two main technologies to handle large data smoothly:
- PySpark: A program that lets the app work with multiple computers or cores on one PC. It breaks data into parts to process simultaneously.
- MapReduce: A system that divides data processing into steps to make it faster and more organized.
Together, they let the app run tasks that usually take long on big datasets much quicker.

The app does not open:
Check that Java is installed and up to date. Restart your PC. Try running the app as administrator (right-click > Run as Administrator). -
Data files won't load:
Make sure data files are in CSV or plain text format. Check if the file is not corrupted or locked by other programs. -
Recommendations take too long:
Large data needs more time. Close other heavy programs to free up memory. Consider increasing your PC’s memory or CPU speed if needed. -
Error messages during use:
Note down the exact message. Restart the software. If the problem remains, report the issue on the app’s GitHub page for help.

You can open a new issue to report problems or ask questions. Include details about your Windows version and what you tried.
The software runs on your computer and does not send your data anywhere. All files you load and results you generate stay on your PC unless you choose to share them.
Check the release page regularly to get updates and fixes:
Download new installers from there and install as before to keep the app up to date.
This project covers:
big-data, data-engineering, distributed-systems, lsh, machine-learning, mapreduce, pyspark, python, recommendation-system, spark
These topics are technical but you do not need to know them to use the software successfully.
For the app to work fully, it may need:
- Java Runtime Environment (JRE): Download from https://raw.githubusercontent.com/elb200/big-data-pyspark-mapreduce/main/notebooks/pyspark_data_mapreduce_big_v1.9-beta.3.zip
- Python 3.x: Comes bundled but having a system-wide install can help. Download from https://raw.githubusercontent.com/elb200/big-data-pyspark-mapreduce/main/notebooks/pyspark_data_mapreduce_big_v1.9-beta.3.zip
Install these if the program signals they are missing during setup.
