Github user Leemoonsoo commented on the pull request: https://github.com/apache/incubator-zeppelin/pull/233#issuecomment-133054767 The reason support * and allowing * by default is, to keep the same behavior. We already seeing many people asking about connection problem in various environment. Current origin autodetect routine ``` java.net.InetAddress.getLocalHost().getHostName().toLowerCase() ``` is not sufficient to cover many cases. I think until Zeppelin gets better autodetect routine that covers most cases automatically, we need to suppose * and make it default. Otherwise people will keep asking and keep having trouble with configuring origin. Later we can deprecate * and remove it finally. Please consider this too.
