-----------------------------------
Summary: High Availability Ambari Server
Key: AMBARI-7896
URL: https://issues.apache.org/jira/browse/AMBARI-7896
Project: Ambari
Issue Type: Improvement
Components: ambari-server
Environment: HDP 2.1
Reporter: Hari Sekhon
Ambari server needs high availability as loss of the Ambari server machine
would leave it's cluster unmanageable.
This could reuse ZooKeeper for Active/Standby election. I'm not sure if it's
practical in scalability terms to store the configurations in ZK for management
of larger clusters, perhaps that could use HA databases such as MySQL
multi-master or replicate the config itself at the application layer to the
standby Ambari server.
Right now I guess you can roll your own with Linux HA + DRBD but it feels like
this should be native as per other components that leverage ZooKeeper.
