> Key: AMBARI-4016
> URL: https://issues.apache.org/jira/browse/AMBARI-4016
> Project: Ambari
> Issue Type: New Feature
> Reporter: Peter Shi
> Labels: HA
>
> 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.
