> Our team has a fork of ambari 1.4.1, we need ambari service to be HA. 
> But seems currently not supported.
> Whether we can implement ambari HA like this
> 1)	Deploy 2 ambari-server with it database in 2 machine, say primary and backup;
> 2)	Sync data from primary database to backup database(using postgresql streaming sync)
when have data updated.
> 3)	Use heartbeat between the 2 ambari-server to discover server_lost event, and make
backup server to be primary; and the new backup server stop communicate with ambari-agent
> 4)	Each agent have 2 ambari-server’s address configurations(or negotiate from zookeeper?),
once primary server changed, agent should register to new one.
> 5)	Backup webui can redirect page to primary one. GET method REST api can access both
ambari-server
> My question
> a.	Can this works?
> b.	Any other information I need sync or restore other than information in database.
