So I managed to hose up my cluster. Here is what I did:
So all my original services are stil listed in CM but are stopped. Attempting to start any of them pops up an error about requiring additional parcels. The originally installed CDH5 RPMs are still installed. From what I can tell, CM is confused and thinks it should still be using the parcels to provide the services.
How can I get CM to use the installed RPMs?
Solved! Go to Solution.

I found in /etc/hadoop/conf.cloudera.hdfs/__cloudera_metadata__ a configuration item that says "parcels_in_use".
There are also references to the parcel install (/opt/cloudera/parcels) in hadoop-env.sh environment variables.
Can I change these setting on all the servers to fix the issue?

Ok I fixed the issue. Noted for for any other poor soul who does the same thing.
I only removed the CDH parcel and left the Spark2. This caused all the issues with CM unable to restart the cluster. Once I deactived the Spark2 parcel, CM was happy. It pushed the new configs out and was able to start the cluster.
