#1

Hi i have 2 node and am trying to do clustering using Hazel cast using following version but its not working.

Openfire : 4.0.2

HazelCast : 2.2.0

Java : 1.8

what is did :

1.add hazelcast plugin on both node from available plugins.

  1. Change plugins/hazelcast/classes/hazelcast-cache-config.xml add 2 node

ip:5701

ip:5701

  1. go to clustring in admin console and click on Enable on one node.

then It show processing for ever.

if i stop that and reboot both node then on first node it show clustering enabled and show one node and on second show clustering is disabled.


#2

after clustering if i click on Users/Group tab on Admin console it throw following error :

#3

In my experience, although you can enable clustering dynamically, it’s necessary to restart with Openfire 4.x after clustering has been enabled in order to get things working properly.


#4

Have you found a solution to this issue yet? We are experiencing the exact same behavior.


#5

I faces same issues. please provide useful solution.


#6

Two thoughts;

a) Can you provide the complete log file (post it to pastebin or similar) - I suspect that there’s another error earlier on that’s causing the problem.

b) You may be able to avoid the problem (if it’s what I think it is) by not attempting to login to the server until after Clustering has started. Of course, there’s no easy way to determine that, other than by waiting a good few minutes after starting!


#7

I was facing the same problem and found the solution to it.

When you want to put a server in a cluster, just put hazelcast.jar in the plugins folder and restart the server.

In few seconds, the server will auto enable the server as a junior/senior member in the cluster. Discovery of the nodes will take place automatically.

Clicking on the enable button causes this error.
