Mandatory Post-Upgrade Tasks

Depending on the configuration of your cluster and your current Ambari version, you must upgrade any of the following features in your cluster, as described in the following topics:

Upgrading Ambari Infra

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

Upgrading Ambari Log Search

If your cluster includes Ambari Log Search service, you must upgrade it along with Ambari.

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 Configurations

Certain scenarios may require that you modify configurations that Ambari did not upgrade automatically.

Upgrading SmartSense

If your cluster includes the SmartSense service, you must upgrade it after upgrading Ambari.
