---------------------------------------
Summary: Ambari Server HA Phase 1: Provide backup and restore
capability
Key: AMBARI-8068
URL: https://issues.apache.org/jira/browse/AMBARI-8068
Project: Ambari
Issue Type: Improvement
Components: ambari-agent, ambari-server
Affects Versions: 1.7.0
Reporter: Szilard Nemethy
Assignee: Szilard Nemethy
Priority: Critical
Fix For: 2.0.0
If the Ambari server host is lost, there should be capability to provision a
new Ambari server that can be brought up with most of the existing state. We
can assume that the Database would be external and retains its state.
This requires:
Backup feature to periodically backup Ambari non-DB state: keystores,
certificates, Ambari server state, agents states
Restore feature to start an Ambari server from a back up. Also, re-point agents
to the new Ambari server.
