Description

Now that HADOOP-6682 has been fixed, Hadoop should always pass the topology script an IP address rather than a hostname. We should write a test that covers this (specifically that DNSToSwitchMapping#resolve is always passed IP addresses) so users can safely write topology scripts that don't handle hostnames.
