Comment 17 for bug 1721416

This problem is caused by config : Please see below from cluster.json.

                       "global_config": {
                            "external_rabbitmq_servers": "10.204.216.105 , 10.204.216.106, 10.204.216.107",
                            "xmpp_auth_enable": true,
                            "xmpp_dns_auth_enable": true
                        },

The external_rabbitmq_servers list has a space in there. We need to remove that.
