> Project: ActiveMQ Artemis
> Issue Type: Bug
> Reporter: Vilius Šumskas
> Assignee: Gary Tully
> Priority: Major
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Let's say there is a simple Artemis HA master/slave shared storage cluster
> with such configuration:
>
> {noformat}
> <connectors>
> <connector
> name="artemis-master">tcp://internal-cluster-dns-1:61616</connector>
> <connector
> name="artemis-slave">tcp://internal-cluster-dns-2:61616</connector>
> </connectors>
> {noformat}
> The cluster is using static discovery.
>
> Factory on internal clients are using:
> {noformat}
> (tcp://internal-cluster-dns-1:61616,tcp://internal-cluster-dns-2:61616)?ha=true&reconnectAttempts=30&useTopologyForLoadBalancing=false{noformat}
> Those internal clients can successfully connect to the cluster and failover
> works as expected.
>
> However if there is also external clients which use external DNS/IP address
> of the cluster the topology doesn't return correct DNS name and the failover
> fails.
> {noformat}
> (tcp://external-cluster-dns-1:61616,tcp://external-cluster-dns-2:61616)?ha=true&reconnectAttempts=30&useTopologyForLoadBalancing=false{noformat}
> {noformat}
> org.apache.activemq.artemis.core.remoting.impl.netty.NettyConnector:
> AMQ214033: Cannot resolve host java.net.UnknownHostException:
> internal-cluster-dns-1{noformat}
