Uninstall HDF 2.1.3

Hi, Is there any documentation on how to do an uninstall of HDF? I will like to uninstall HDF 2.1.3 and replace with 2.1.2 due to the controller issue. I can see steps to uninstalling HDP but not HDF. I need to be sure i'm not missing out on anything...Anyone gone this route? @Matt Clarke @Matt Burgess @Bryan Bende

Thanks @Matt Clarke

I need the cluster up and running immediately. I opted for the 2.1.2 version of HDF. However, i ran into some issues while it was installing NiFi. Can you guide me on the way forward?

The issue was a cyclic link where HDF 2.1.3 linked /etc/nifi/conf to /usr/hdf/current/nifi/conf while HDF 2.1.2 was linking the other way round. Deleting the previous link resolved the issue. HDF 2.1.2 installed and controllers are fine. Thanks for your guidance @Matt Clarke
