@Sam2020 Logically this is a maintenance upgrade so no much trouble and extra steps needed.  Your steps looks good till "c" i.e once you upgrade Cloudera Manager server to 7.4.4 there is a very simple steps you need, means just activate the Parcels or 7.1.7 that’s it. In layman’s term these steps will look like this.  I am assuming you have the parcels for 7.1.7 available (credentials and repo details). Then follow below steps. 1.) Please stop the cluster services 2.) Navigate to CM -> hosts -> parcels -> Parcel Repository & Network Settings and include the 7.1.7 parcel "Remote Parcel Repository URLs" 3.) Take the back up of the required service databases following the steps below https://docs.cloudera.com/cdp-private-cloud/latest/upgrade-cdp/topics/ug_cdh_upgrade_backup.html 4.)

@GangWar    Hello, This problem has been solved because the atlas service has been deleted, but there are dependencies in other service configurations that have not been cleared.   This can also be seen from the log: ERROR Staleness-Detector-1: com.cloudera.cmf.service.config.components.ProcessStalenessDetector: Failed to check staleness for service client configs : DbService{id=75,name=atlas}   After adding the deleted atlas service back, I succeeded in generating the missing Kerberos credentials again. In short, thank you very much for your reply and wish you a happy life! ... View more
