             Summary: Behavior of "Exclusive Consumer" configured for queues on 
AMQ : Behavior of Master Slave Topology 
                 Key: AMQ-4353
                 URL: https://issues.apache.org/jira/browse/AMQ-4353
             Project: ActiveMQ
          Issue Type: Task
          Components: activemq-leveldb-store, Broker
    Affects Versions: 5.5.1
         Environment: Linux,AMQ 5.5.1
            Reporter: Jessy



I noticed the following behavior when I set “Exclusive consumer” property for a 
queue configured on AMQ 5.5.1 installation

If say for Queue A, there were 2 consumers : con1 and con2 , both consumers are 
up all the time .
Say, one of them con1 becomes the master and consumes the message
Successive message are not consumed by  con1, where-in con2 is also found to 
consume the message..
There is alternative consumption ,once by con1 and con2.

Master is not the master all the time ..even if  master is up,slave consumes 
the message in alternative fashion.
Is this the intended behavior for “Master-Slave” paradigm?
Is there any API exposed to identify which is the master and slave ,which would 
help us in our logging to identify which is the current consumer of the message.
