Subject how to roll back HDP 2.1 -> HDP 2.2 upgrade
Date Sun, 20 Dec 2015 12:35:40 GMT
Running Ambari 2.0.2, I tried to do an upgrade to the HDP 2.2 stack. That upgrade
has been a disaster, and the cluster is totally screwed up. At this point I think my best
bet is to rollback to HDP 2.1 and try again another time. 

I didn’t see a discussion of how to do a rollback. Is this documented somewhere?
If not, can someone provide guidance?
