chengjianyun opened a new pull request #4309:
URL: https://github.com/apache/iotdb/pull/4309
The log shows behaviors like below in meta group:
1. Node 09 run as follower in term 3.
2. Node 09 heartbeat timeout in term 3.
3. Node 09 update its term to 4
4. Node 09 update `voteFor` to null
5. Node 09 receive a election from Node 08 in term 4, accept the election, become follower of group in term 4.
6. Node 09 continue to election. but term is 5.
It's not right in the step 6 as Node 09 timed out in term 3, it only start the election for term 4 instead of term 5. I think the behavior isn't by design although system didn't run into some wrong status.
Attach log.
