---------------------------------------

             Summary: external clients cannot use cluster topoligy 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


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:
{code:java}
(tcp://internal-cluster-dns-1:61616,tcp://internal-cluster-dns-2:61616)?ha=true&reconnectAttempts=30&useTopologyForLoadBalancing=false{code}
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}
