------------------------------------------
Summary: Automatic Client failover is not working
Key: ARTEMIS-2589
URL: https://issues.apache.org/jira/browse/ARTEMIS-2589
Project: ActiveMQ Artemis
Issue Type: Bug
Components: ActiveMQ-Artemis-Native
Affects Versions: 2.10.0, 2.6.4
Reporter: richard krasowski
Assignee: Clebert Suconic
+*Problem*+:
Automatic Client failover (reconnection due to server shutdown) is not working
properly.
*+Description+*:
I created a live/backup group over server-discovery mechanisms. They both
broadcast their connectors over udp and a multicast address. When the both
servers (live and backup) are started, they are successfully recognized as live
and backup.
I have 2 clients both implemented in Java Spring. One client acts as the
producer and one client acts as consumer. They are configured over a
ActiveMQJMSConnectionFactory and over DiscoveryGroup mechanisms
(udp://{color:#008000}231.7.7.7:{color}{color:#0000ff}9876){color}. The
producer has a jmsTemplate and the consumer is realized as a Message driven
bean.
When I send 20 messages over the producer the live server acknowledges them and
forwards them to the consumer. When I shutdown the live-server the consumer
successfully failover to the backup server but the producer says: "*Backup is
not active, trying original connection configuration now.*"
And after a minute it throws an Error "*org.apache.activemq.artemis.core.client
: AMQ214016: Failed to create netty connection*" with an
*java.net.UnknownHostException*:
It seems like the client receives the live/backup configuration and tries to
reconnect to live server but after that it does not successfully failover to
backup server.
I created a github repo with a docker-compose environment. There is a producer,
a live/backup artemis broker pair and a consumer.

My goal is to send 200 messages and during the sending process I want to
shutdown the server (activemq0) and I want to see a successful client failover
of the producer to backup server (activemq1)
