MapReduce in Go

This directory contains the Go implementation of the MapReduce framework. For detailed information about the project, please see the main README.

Getting Started

Prerequisites

• Go 1.16 or later
• Make (optional, for using Makefile commands)

Running a WordCount Example

1. Build the main application:

   go build -o mr_main src/main.go

2. Build the WordCount plugin:

   go build -buildmode=plugin -o apps/wordcount.so apps/wordcount.go

3. Run workers:

   ./mr_main mrworker apps/wordcount.so & ./mr_main mrworker apps/wordcount.so

4. Run coordinator:

   ./mr_main mrcoordinator files/pg-*

Creating Custom MapReduce Tasks

To create your own MapReduce task, implement the Map and Reduce functions in a new Go file, following the pattern in apps/wordcount.go.
