Adding and configuring a new Hue service on a new host
To migrate the Hue service from one host to another within the same cluster, you can add a new Hue service on a new host using the Add Service wizard and manually configure the Hue service as needed.
- Sign in to Cloudera Manager as an Administrator.
- Go to Clusters > Hue service and stop the Hue service by clicking Actions > Stop.
- Go to Clusters > [***CLUSTER-NAME***] and click Add Service from the menu.
- On the Add Service wizard, select Hue.
-
On the Select Dependencies page, select the
Optional Dependencies.
-
On the Assign Roles page, click the field below
Hue Server and Load Balancer
roles. This launches a dialog box where you can select hosts where you want to
add the role.
Click OK after making your selection.
-
On the Setup Database page, specify the details of your
existing Hue database.
- Select your database vendor from the Type field and specify the Database Hostname, Database Name, Username, and Password of your existing database.
- Click Test Connection, and when the success message appears, click Continue.
The wizard configures and starts Hue and its dependent services. - After the new Hue service is in the running state, configure the Hue Advanced Configuration Snippet as it is in the existing Hue service on the older host.
- Click Save Changes and restart the Hue service.
- Verify that the new Hue service functions as expected.
- Delete the Hue service from the old host by clicking Actions > Delete.
