This is a known bug in that version of RabbitMQ. Please upgrade to the latest version.

When I used

rabbitmqctl join_cluster rabbit@ip

I got this error，then I use

rabbitmqctl join_cluster rabbit@hostname

You can use rabbitmqctl status for more information.

[root@node1 ~]# rabbitmqctl status
Status of node rabbit@node1 ...

Which means you current node name is node1, and you should use rabbitmqctl join_cluster rabbit@node1 command. Sometimes the RABBITMQ nodename is NOT the same as HOSTNAME.

According to this method, you can doublecheck EXACT node name of both this and target instance and then create correct adding-cluster command.
