How to install Hadoop on your local Kubernetes cluster

Okey this is not the easiest way of running Hadoop on your local computer and probably you should instead just install it locally.

However if you really insist doing this here's how:

1. Install kubectl, minikube and Docker if you don't already have it. I recommend using package-manager like Chocolatey. Minikube should install with VirtualBox as default driver which I recommend. When starting minikube we should increase its memory limit since our Hadoop node's pods need at least 2GB: minikube --memory 4096 --cpus 2 start (minikube's default is 1GB). NOTE: actually the Hadoop cluster by default uses about 10GB in memory limits and about 3GB running memory. From what I looked my k8s will overprovision to 300% of its capacity limits but use far less.
2. Install helm. Then run helm init.
3. Now you

Install psql on WSL

Home

This install is pretty different from previous versions of psql install instructions for windows. This install uses the WSL and Ubuntu shell.

We are installing this through the Ubuntu command line which is different from the other Ubuntu install instructions because those instructions use Ubuntu's GUI, which we don't have access to here.

NOTE: Since this is a service that is running on Ubuntu, you should be in the the Ubuntu file system when running these commands!
