Stopping or Restarting the Cloudera Manager Server
You can stop the Cloudera Manager server (for example, to perform maintenance on its host) without affecting the other services running on your cluster. Statistics data used by Activity Monitoring and Service Monitoring will continue to be collected during the time the server is down.
To stop the Cloudera Manager server without affecting other services:
service cloudera-scm-server stop
To restart it:
service cloudera-scm-server start

If you are intending to perform an upgrade of Cloudera Manager, then you should stop the management service (through the Admin Console) prior to stopping the server.
