Deploy the Cluster Services
After you finish the wizard and deploy the cluster, some services might fail to start. If this is the case, you can start those services individually by launching them from the Ambari dashboard Services pane.
Steps
From Ambari's left-hand Services pane, click the service you want.
From the Quick Links drop-down, select the UI option.
Find links for the SAM UI under Streaming Analytics Manager and for the Schema Registry UI under Registry.
Result
The UI for your HDF service opens in a new window.
