             Summary: Provide a mechanism to migrate from single to multiple masters
                 Key: KUDU-1474
                 URL: https://issues.apache.org/jira/browse/KUDU-1474
             Project: Kudu
          Issue Type: Sub-task
          Components: master
    Affects Versions: 0.8.0
            Reporter: Adar Dembo
            Assignee: Adar Dembo
            Priority: Critical
             Fix For: 1.0.0


We need a mechanism to convert a single-master setup into a multi-master setup. It'll probably rely on remote bootstrap in some capacity, and could conceivably be used to repair a master in the event that it needs to be rebuilt.

I haven't given this any thought. I'm also wondering out loud whether such a mechanism would be sufficient for a CLI tool that adds new masters or removes old masters from a Raft configuration.
