Description

As discussed in the mailing list, we are using InetAddress.getLocalHost().getHostAddress() for the org.apache.samza.coordinator.server.HttpServer#getUrl. But getLocalHost() may return a loopback address, 127.0.0.1, which is not reachable by other machines.

This idea is to filter out the loopback address. One possible solution is here, use NetworkInterface.getNetworkInterfaces() .
