3. Post-Upgrade Tasks

Depending on the configuration of your cluster and the Ambari version you are starting with, review the following post-upgrade tasks.



Upgrading Ambari Metrics

If your cluster includes the Ambari Metrics System (“AMS”) service, you must upgrade the system along with Ambari. This will include adding the Grafana component to the system.

Adding Grafana to Ambari Metrics

Grafana is now included as a component of Ambari Metrics. If you are upgrading from Ambari 2.2.1 or earlier, and your Ambari Metrics service does not contain Grafana, proceed to add Grafana to Ambari Metrics.

Upgrading SmartSense

If your cluster includes the SmartSense service, you must upgrade it along with Ambari.

Upgrading Configurations

Certain scenarios may require that you modify configurations that Ambari did not upgrade automatically. Review scenarios described in this section for information about upgrading configurations in your cluster.
