Managing Clusters
Cloudera Manager can manage multiple clusters, however each cluster can only be associated with a single Cloudera Manager Server or Cloudera Manager HA pair. Once you have successfully installed your first cluster, you can add additional clusters, running the same or a different version of CDH. You can then manage each cluster and its services independently.
On the tab you can access many cluster-wide actions by selecting
to the right of the cluster name: add a service, start, stop, restart, deploy client configurations, enable
Kerberos, and perform cluster refresh, rename, upgrade, and maintenance mode actions.
