There are several requirements that need to be considered when setting up multiple Ambari Server “standalone” instances:
Ambari Server instances should be the same version.
The Ambari Server instances should point to the same underlying database.
Ambari database should be scaled and made highly-available, independent of Ambari Server.
If using an external authentication source (such as LDAP or Active Directory), Ambari Server authentication should be configured the same for all Ambari Server instances.
If the cluster you are accessing with Views is Kerberos-enabled, you need to configure Ambari and the Views for Kerberos.
Run the multiple “standalone” Ambari Server instances behind a Reverse Proxy.
After your standalone Ambari Servers are setup and configured, you can configure the views to communicate with your HDP cluster.
