ARTEMIS-2868 Protect Topology Updates from Split Brain on broker shutdown as
well
> Split Brain on Replication could "damage" the Topology, isolating the server
> ----------------------------------------------------------------------------

> 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 10m
> 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.
