environment: ubuntu 12.04 server, ip 10.6.4.52
openfire 3.8.2
hazelcast version 1.0.6 added in the plugin page
failed in the first step of following tutorial:
http://vincentpaca.github.io/2013/05/23/openfire-plus-hazelcast-clustering-on-am azon-ec2/
I changed the hazelcast-cache-config.xml with following:
<network>
<port auto-increment="true">5701</port>
<join>
<multicast enabled="false"/>
<tcp-ip enabled="true">
<hostname>10.6.4.52:5701</hostname>
</tcp-ip>
<aws enabled="false"/>
</join>
<interfaces enabled="true">
<interface>10.6.4.52</interface>
</interfaces>
when I enable the cluster in the admin console, it shows failed to join in the cluster and here is the error in the log file:
