> The default ScriptBasedMapping implementation of DNSToSwitchMapping for
> determining cluster topology has some drawbacks. Principally, it forks to an
> OS-specific script.
> This issue proposes two new Java implementations of DNSToSwitchMapping.
> TableMapping reads a two column text file that maps an IP or hostname to a
> rack ID. Ip4RangeMapping reads a three column text file where each line
> represents a start and end IP range plus a rack ID.
