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