> Persist commit index in Raft log.

> Key: RATIS-352
> URL: https://issues.apache.org/jira/browse/RATIS-352
> Project: Ratis
> Issue Type: Improvement
> Components: server
> Reporter: Tsz Wo Nicholas Sze
> Assignee: Tsz Wo Nicholas Sze
> Priority: Major
> Attachments: r352_20181024.patch
>
>
> Current the commit index is not persisted in the Raft log. When a server
> restarts, it cannot apply its log until it has joined a Raft group. There is
> no problem if there is a Raft group.
> However, a server cannot recover its data when formatting a Raft group is
> impossible (e.g. a majority of servers are dead). Ideally, a server can
> safely apply the log up to the commit index. The JIRA is to persist the
> commit index so that such recovery is possible.
