----------------------------------
Component/s: replicated log
> Support catch-up replicated log
> -------------------------------
>
> Key: MESOS-736
> URL: https://issues.apache.org/jira/browse/MESOS-736
> Project: Mesos
> Issue Type: Improvement
> Components: replicated log
> Reporter: Jie Yu
> Assignee: Jie Yu
> Labels: twitter
> Fix For: 0.16.0
>
>
> When a replica joins Paxos with an empty log, we don't allow this replica to
> fully participate in Paxos immediately. Instead, this replica is treated as a
> non-voting member, meaning that it will not reply to any requests from other
> replicas. It simply learns those log entries that have been agreed on and
> tries to catch up the leader. When the catch-up process is done, we re-admit
> this replica to Paxos and allow it to vote.
> If we have a disk failure and want to swap a master machine, we can simply
> start the scheduler on a new machine with an empty log (and that's it).
