Access Big Data Cloud Using Ambari

This topic does not apply to Oracle Cloud Infrastructure. On Oracle Cloud Infrastructure, the Ambari port is already accessible and nothing else needs to be done.

You can use Apache Ambari to access and manage Oracle Big Data Cloud clusters. While Ambari isn't needed for normal operations with the cluster, it's useful to open Ambari access to help with troubleshooting and certain administrative actions.

To access a cluster using Ambari, you enable an access rule to open the port for Ambari, and then use the Ambari URL:

1. Open the service console. See Access the Service Console for Big Data Cloud.
2. From the menu for the cluster you want to access using Ambari, select Access Rules. Access rules control which ports can be accessed on the VMs that are part of a cluster.
3. In the list of access rules, find the Ambari REST rule, which is associated with port 8080, the port that needs to be open.
4. From the menu for the Ambari REST rule, select Enable.

   The Enable Access Rule window is displayed.

5. Select Enable.

   The Enable Access Rule window closes and the rule is displayed as enabled in the list of rules. The given port on the cluster is opened to the public internet.

6. After the rule is enabled, click the link for the cluster at the top of the page to return to the cluster overview page.
7. On the cluster overview page, under Resources, find the MASTER-1 host, copy the Public IP address, and paste it into your browser address bar, adding port 8080 if necessary. For example, https://Public_IP_address:8080/. You must use https or you won’t be able to connect.
8. If you’re prompted for credentials, enter the user name and password specified for the cluster when the cluster was created.

   You should now be connected to the Ambari management console on the cluster.
