4. Renaming a Cluster

After you have created a cluster, you can rename the cluster using the Rename Cluster function.

To rename a cluster:

  1. In Clusters, click the Rename Cluster icon, next to the cluster name.

    The cluster name becomes write-able.

  2. Enter alphanumeric characters as a cluster name.

  3. Click the check mark.

  4. Confirm.


After renaming the cluster, alert checks must be re-queued on the agents. Therefore, you must restart Ambari Server and the Ambari Agents for the change to take effect.


By changing the name of the cluster, the Ambari REST API resource for the cluster also changes. You must adjust any API calls you make to use this new name.
