Node02 unable to join cluster after upgrade from 7.13.0 to 7.13.7

Hi, 

We had a working Confluence TST cluster with 2 nodes on version 7.13.0.

After updating both nodes to version 7.13.7 we have the following behavior:

  • node 1 starts just fine
  • once node 1 is completely started we start node 2
  • In the logs we see error messages about the authentication to the cluster and asking to verify the cluster name and secret (both are ok and the same on both nodes)
  • Node 2 than takes the cluster and node 1 get's an error 'Could not open Hibernate Session for transaction; nested exception is com.hazelcast.core.HazelcastInstanceNotActiveException: Hazelcast instance is not active!'

When we then restart node 1, we have the same behavior (node 1 is ok but node 2 crashes with the same error).

So there seems to be a problem with the cluster after the update.

On both machines port 5801 is open on the firewall.

Any ideas?

The WARN that you are seeing is in reference to your confluence.cfg.xml in your home directory. It looks like the following two properties:

<property name="confluence.cluster.authentication.enabled">true</property>
<property name="confluence.cluster.authentication.secret">some_secret</property> 

 

Verify that the secret is the same on both your servers. After making them the same for our servers, all nodes were able to join the cluster
