Hi all   So I managed to hose up my cluster. Here is what I did: Installed CDH 5.11.1 on my Centos7 cluster using RPMs via CM and everything is working One of my devs asked for Spark2 on the cluster Attempted to install the Spark2 parcel on the cluster but it complained about missing CDH5 parcel dependency Installed the CDH 5.11.1 parcel (big mistake!) Installed Spark2 parcel Spark2 stuff didn't seem to be working right due to library issues. Probably because parcels and RPMs were both installed Removed the CDH parcel which left the cluster in a funky state   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?   Help! ... View more
