> Project: Hadoop Core
> Issue Type: Bug
> Components: io
> Affects Versions: 0.21.0
> Environment: at home, incomplete networking, exploring the consequences
> Reporter: Steve Loughran
> Priority: Minor

> if the local IPAddr is loopback, then reverse DNS lookup fails. It may be better to recognise this state and return localhost in such a situation, rather than try to look up 1.1.0.127.in-addr.arpa
