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. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
