how to fully uninstall worker/kafka machine after delete it from ambari cluster

avatar

as all know we can delete the worker/kafka machine from the cluster but configuration on the host still exist

our target is: full host uninstall ( include re-filesystem , delete rpm's , delete users , file , conf etc ) , and then full new installation by API commands to join host to the cluster

what we do until now is that:

delete the worker07 from the ambari cluster

re-create file-system on all disks as /dev/sdc /dev/sdd , etc



but the big problem now is how to un install the rest configuration as users , rpm's and other stuff

please advice how to continue ?

what are the doc if exist for this proccess?
