Description

The web interface, for example http://$MASTER_HOST:50030/machines.jsp, uses internal hostnames when running on EC2. This makes it impossible to access from outside EC2.

The slaves file has the public names listed. Resolving a public name inside EC2 returns the private IP (which would reverse to the internal DNS name).
