Description:
!image-2024-05-10-16-12-25-436.png|width=888,height=376!
The event sequence that triggered IllegalStateException:
# Raft Group (A, B, C) with leader A.
# Client cli adds a new Peer D to the group.
# Leader A sends snapshot and logs to D, and peer D is successfully
bootstrapped.
# The configuration change log (A,B,C,D) is *NOT* committed while B timeouts,
starts an election, becomes the new leader.
# Client cli re-send the add-peer-D request to the newly elected leader B.
# B thoughts the D is a new peer with next-index = 0, tries to send the
snapshot to D. D already had the snapshot, so the IllegalStateException
occurred.
