Song Ziyang updated RATIS-2029:
-------------------------------
Description:
Scenario:
Old cluster contained a RaftGroup G with peers (A, B, C).
After shutting down old cluster, we started a new cluster which also contained
a RaftGroup G with peers (B, C, D).
A and D both have a same RaftPeerID 0.
However, by mistake, A is not properly shut down and will still send out
RequestVote RPCs. The new cluster group will consider A a member of the group
since it has a valid raft peer id and *won't shut it down.* (see the logs, 0
rejects a requestVote from peer 0)
Currently we only identify a peer through \{peerId}@group-${groupId}. I am
wondering if there's way to tell a peer's comm address in the requestVote log
messages.
cc [~tanxinyu]. Also what do you think [~szetszwo] ?
