Play Framework 2 error: "nodename nor servname provided, or not known"
Then there was me fiddling with play framework... and in the first time I ran the sample application a beautiful stack trace with this exception poped up:
Caused by: java.net.UnknownHostException: [HOSTNAME_NAME]: nodename nor servname provided, or not known
After some research I found out that the issue is a bug in JDK 7 for OSX. It seems it doesn't recognize your hostname as localhost, so the workaround is pretty easy:
Add in your hosts file your hostname pointing to 127.0.0.1
$ sudo echo "127.0.0.1 [YOUR_HOSTNAME]" >> /etc/hosts
Important: do not delete your "127.0.0.1 localhost" entry in /etc/hosts because it's used to configure the loopback interface when the system is booting
