@sass Cloudera agent is still needed you can't remove that. If there is no way then after removing you have to install agent packages again.

@sharathkumar13 Technically the other services will keep running. But managing the services without CM is difficult however you can perform task using command line for some services but that’s a tedious task. So CM is essential to monitor the services.
