Migrate to Ambari Alerts and Metrics

If your cluster includes legacy Nagios and Ganglia services, they must be removed and replaced with Ambari Alerts and Metrics.

Adjusting for Kerberos

If you have upgraded from Ambari 1.7 or earlier and your cluster was configured for Kerberos, you must adjust Ambari.

Upgrade Ambari Metrics

If your cluster includes the Ambari Metrics System (“AMS”) service, you must upgrade the system along with Ambari.

Upgrading SmartSense

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