1) I set the join.type to aws,
2) I start the start node,
3) first node join the cluster.
4) start the second node (second node also has same confluence.cfg.xml
5) Second node join, first node unexpectedly is removed from the cluster
<property name="confluence.cluster">true</property>
<property name="confluence.cluster.aws.iam.role">my-iamrole-desc-ec2-tag</property>
<property name="confluence.cluster.aws.region">us-west-2</property>
<property name="confluence.cluster.home">/usr/local/confluence/confluence-home/shared-home</property>
<property name="confluence.cluster.join.type">aws</property>
What other config files I need to update to support more than one node in the cluster.
