Do we need to stop or put all hadoop services in maintenance, during our DB patching activity or just putting Cloudera Manager in maintenance mode will suffice?
The clean and recommended way is to stop those services which are affected, before the backend database is shut down for maintenance (e.g. during maintenance window).
