> ------------------------------------------------------------------
>
> Key: HADOOP-3862
> URL: https://issues.apache.org/jira/browse/HADOOP-3862
> Project: Hadoop Common
> Issue Type: New Feature
> Components: net
> Reporter: Owen O'Malley
>
> We should have a Java class that answers network topology questions by implementing DNSToSwitchMapping by using the host's IP address and a mask that defines the addresses that are on the same rack. Therefore, if your racks are defined by using the top 3 octets, you'd configure ff.ff.ff.00.
