> Fix java.lang.IllegalStateException: "gap between entries"
> ----------------------------------------------------------

> Key: RATIS-2507
> URL: https://issues.apache.org/jira/browse/RATIS-2507
> Project: Ratis
> Issue Type: Bug
> Reporter: Sammi Chen
> Assignee: Sammi Chen
> Priority: Major
> Time Spent: 1h
> Remaining Estimate: 0h
>
> RaftLog end log index is smaller than last snapshot index during RaftServer
> startup, it indicates that raft log state and state machine state is
> inconsistent.
> In this case, it's better to fail the RaftServer, instead of currently log a
> WARN message and continue.
> A real case, is an OM failed to install snapshot and terminate itself. The on
> disk state machine state(rocksdb) and raft log files are from different
> source, state machine data from leader, raft log files are local, and
> snapshot index get from state machine is bigger than raft log end index,
> which further cause another issue.
> Refer to https://issues.apache.org/jira/browse/HDDS-15103 to get more info.
