Since THPA comprises of 2 components custom kube-controller-manager and scheduler-extender so 
we need to modify these:

*** set nodes label ***

- For worker nodes, set the following label to them: node-role.kubernetes.io/worker=true

*** kube-controller-manager ***

- cd to kube-controller-manager directory.

- Copy binary file "kube-controller-manager" to home directory.

- Copy kube-controller-manager.yaml to /etc/kubernetes/manifests/

- After copying, the kube-controller-manager pod will automatically be restarted.

*** scheduler-extender *** 

- cd to scheduler-extender directory

- copy files "scheduler-extender-config.yaml" and "scheduler-extender-policy.json" to /etc/kubernetes/

- copy file "kube-scheduler.yaml" to /etc/kubernetes/manifests/

- cd to k8s-scheduler-extender directory

- execute "go build ."

- Run the executable file because the scheduler extender run as a server that is triggered whenever new pod need to be scheduled.
