Example of Kustomized Helm Install
(Using Helm's Post Rendering Feature)

Overview: Why would you want to do this?

Background Context:

• Question: What is a helm chart?
• Answer: helm charts are just templating engines that render generated yaml
  • input variables (with a mix of default and override values for those variables)
  • get plugged into golang templatized yaml
  • and output a wall of text of generated yaml
• Community Helm Charts:

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
