Prerequisites For Standalone Ambari Servers
When setting up multiple standalone Ambari Server instances, you must be aware of the following requirements:
All Ambari Server instances should be the same version.
The main Ambari Server should be on its own database instance. All other standalone instances should share the same one.
Ensure that it is not the same database that is being used by the Operational Ambari Server that is managing the HDP cluster.
The Ambari database should be scaled and highly available, independent of Ambari Server.
For an external authentication source such as LDAP or Active Directory, Ambari Server authentication should be identical for all instances.
If the cluster that Views users access is Kerberos-enabled, you must configure Ambari and the views for Kerberos.
You must run each standalone Ambari Server instance behind a reverse proxy.
