> Protect a replicated broker pair from breaking the topology in case of a split brain

> Key: ARTEMIS-2868
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2868
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Affects Versions: 2.14.0
> Reporter: Clebert Suconic
> Priority: Major
> Fix For: 2.15.0
>
> Time Spent: 1h 20m
> Remaining Estimate: 0h
>
> The issue is that after a split brain, during a reconnect the live broker will send a topology update to the live replacing the topology.
>
> As a result, new replicas will not be able to reconnect after the split brain, since the topology will return a wrong address, probably towards itself from backup.
