Erase HDP 2.x and Ambari

Since I hack now often with Hortonworks HDP, I also often need to completely clean out my lab environments to get fresh boxes. I figured to write a ugly shell script is more comfortable as bothering my infra guys to reset the VM's in Azure - which also reset all my modifications. Bad!
Anyhow, here's the script in the case anyone has some use, too.

https://github.com/alo-alt/shell/blob/master/rmhdp.bash

As usual, first stop all Ambari managed services. I remove Postgres too, since the setup of a new db done by the installer of Ambari is much more faster than dealing with inconsistencies later.
Side Note: The script is made for RHEL based distributions ;)
