# Hadoop-YARN-k8s Sandbox
This is a sandbox for running a Hadoop YARN cluster on Kubernetes (using Minikube).
The sandbox can be started with a single command and will bring up a Hadoop YARN cluster with 2 datanodes, 1 namenode and 1 resource manager.
The various web interfaces for the cluster are proxied and exposed on the host machine automatically and can be accessed via the URLs listed below.
> [!WARNING]
> The sandbox is intended to be used for testing and development purposes only.---
### Prerequisites
* Minikube
* GNU Make
* Docker [`buildx` CLI plugin](https://github.com/docker/buildx?tab=readme-ov-file#installing)### System Requirements
* Minikube should have at least 8GB of memory and 4 CPUs for the sandbox to run properly (This can be changed in the `Makefile`).---
### Running
* Run `make deploy` to deploy the system.
* Run `make clean` to bring down the system (All data will be lost!)#### Running spark jobs
* Run `make spark_exec` to exec into the spark pod.
* The `work` directory is mounted as `/work` in the spark pod. You can copy your spark job to this directory and run it using `spark-submit`. (Use `--master yarn` to run the job on the YARN cluster.)
* Or you can enter the spark shell using `spark-shell --master yarn` and run your spark jobs interactively.#### Managing the cluster or running MapReduce tasks
* Run `make shell` to exec into the `dfsadmin` pod.
* You can run HDFS commands using `hdfs dfs` or run MapReduce jobs using `yarn jar`.---
