Gary Tully commented on ARTEMIS-3640:
-------------------------------------
I don't think so, but I could be wrong. The server locator should be content to
make contact on one of the URLs.
It is true that from an external client perspective one of the URLs won't ever
resolve.
> external clients cannot use cluster topology for HA or load balancing

> Key: ARTEMIS-3640
> URL: https://issues.apache.org/jira/browse/ARTEMIS-3640
> Project: ActiveMQ Artemis
> Issue Type: Bug
> Reporter: Vilius Šumskas
> Assignee: Gary Tully
> Priority: Major
>
> 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}
