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.
Next Steps
Restart services, only after you complete all applicable, post-upgrade tasks.
