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. - For more information on JIRA, see: http://www.atlassian.com/software/jira
