## What it is
A set of Docker images and shell scripts for spinning up a multi-node Hadoop cluster (1 master, N slaves) inside Docker containers. It includes scripts to start containers, launch Hadoop, resize the cluster, and run a sample wordcount job.

## Use cases
- set up a hadoop cluster locally with docker
- learn how hadoop multi-node clusters work
- run a 3-node hadoop cluster for testing
- spin up an arbitrary-size hadoop cluster in containers
- demo mapreduce wordcount on hadoop
- sandbox environment for big data experiments

## When to choose
- you want a quick local Hadoop cluster for learning or demos without provisioning real machines
- you need a reproducible multi-node Hadoop sandbox for testing MapReduce jobs

## When to avoid
- you need a production-grade Hadoop deployment with resource management and persistence
- you want a modern big data stack (e.g., Kubernetes-based Spark or Hadoop operators)

## Facets
- artifact type: infra-config
- maturity: maintenance
- function: container-runtime, deployment, developer-tools
- domain: big-data, microservices
