             Summary: Cannot Recover AMQP Subscription Existing On Remote Cluster Member 
                 Key: ARTEMIS-1556
                 URL: https://issues.apache.org/jira/browse/ARTEMIS-1556
             Project: ActiveMQ Artemis
          Issue Type: Bug
          Components: Broker
    Affects Versions: 2.4.0
         Environment: Latest broker snapshot running on fedora 26. AMQP .Net Lite client. 
            Reporter: Todd Baert


Assuming broker1 and broker2 exist in a cluster, if an AMQP Source constituting a shared durable subscription (having capabilities "shared", "global" and "topic") is created on broker1, and attempted to be recovered from a client connected to broker2 (by creating an attach frame with a null source, with desired capabilities  "shared", "global" and "topic"), an Amqp.AmqpException is thrown.

In a cluster, shouldn't it be possible to recover subscriptions that exist on another broker? Shouldn't the search for this subscription occur on all cluster members?

I don't believe this is happening. It looks like we just search locally:

See code below from x (comments are not my own, they are from source):
{code:java}
      if (source == null) {
         // Attempt to recover a previous subscription happens when a link reattach happens on a
         // subscription queue
         String clientId = getClientId();
         String pubId = sender.getName();
         global = hasRemoteDesiredCapability(sender, GLOBAL);
         queue = createQueueName(connection.isUseCoreSubscriptionNaming(), clientId, pubId, true, global, false);
         QueueQueryResult result = sessionSPI.queueQuery(queue, RoutingType.MULTICAST, false);
         multicast = true;
         routingTypeToUse = RoutingType.MULTICAST;

         // Once confirmed that the address exists we need to return a Source that reflects
         // the lifetime policy and capabilities of the new subscription.
         if (result.isExists()) {
{code}
