MapReduce in Go

A simple distributed application exercise for ordering datasets using MapReduce to be implemented in one month during the Distributed Systems and Cloud Computing course.

---

Instructions

1) Create the Go module

$ go mod init mapReduce
$ go mod tidy

2) Compile gRPC definition files

$ protoc --go_out=. --go-grpc_out=. mapreduce/master.proto
$ protoc --go_out=. --go-grpc_out=. mapreduce/reducer.proto

3) Run the programme

$ go run main.go

---

Run the program to start the MapReduce system. Master, Mapper and Reducer nodes will be simulated on the same machine, and the results will be saved to file.
