Glen Geng updated RATIS-998:
----------------------------
Description:
shouldWithholdVotes() should be triggered for handling higher term. If
currentTerm is larger or equal to candidateTerm, just reject the request vote,
no need further handling.
Current code is
{code:java}
private boolean shouldWithholdVotes(long candidateTerm) {
if (state.getCurrentTerm() < candidateTerm) {
return false;
} else if (isLeader()) {
return true;
} else {
// following a leader and not yet timeout
return isFollower() && state.hasLeader()
&&
role.getFollowerState().map(FollowerState::shouldWithholdVotes).orElse(false);
}
}
{code}
Modify to
{code:java}
private boolean shouldWithholdVotes(long candidateTerm) {
if (state.getCurrentTerm() >= candidateTerm) {
return false;
} else if (isLeader()) {
return true;
} else {
// following a leader and not yet timeout
return isFollower() && state.hasLeader()
&&
role.getFollowerState().map(FollowerState::shouldWithholdVotes).orElse(false);
}
}
{code}
