             Summary: Java client library tries to connect to a stopped Infinispan instance over HotRod
                 Key: ISPN-7747
                 URL: https://issues.jboss.org/browse/ISPN-7747
             Project: Infinispan
          Issue Type: Bug
          Components: Remote Protocols
    Affects Versions: 8.2.6.Final
         Environment: I have a Infinispan cluster with 4 instances on 4 nodes. There is approx. 16 GB of data on each node. Replication factor is two.
4 Java instances are running on the same hosts and connect to the cluster via HotRod.
            Reporter: Daniel Breitlauch


When I stop one instance of Infinispan I see it rebalancing for e few seconds. I also see the topology change propagated to the java clients.

But there seems to be a problem in the java client library. After the topology change it looks like it tries to connect to the Infinispan instance that was stopped.

At least I see these SocketTimeoutExceptions:
{code:java}
java.net.SocketTimeoutException: null

{code}

Is this a known issue? Is Infinispan not reachable while rebalancing?
