The FAQ says: "When a broker starts up, it registers its ip/port in ZK. You need to make sure the registered ip is consistent with what's listed in metadata.broker.list in the producer config. By default, the registered ip is given by InetAddress.getLocalHost.getHostAddress. Typically, this should return the real ip of the host. However, sometimes (e.g., in EC2), the returned ip is an internal one and can't be connected to from outside. The solution is to explicitly set the host ip to be registered in ZK by setting the "hostname" property in server.properties. In another rare case where the binding host/port is different from the host/port for client connection, you can set advertised.host.name and advertised.port for client connection."
Can somebody give an example for that "rare case" where the binding host/port is different from the host/port for client connection? Cheers, Eugene
