Hadoop Slave Configuration support with regular expressions
Hi, Instead of explicit ip or host name in slave machines, would it be possible to provide host name int he form of regular expression say teja* to say all machines on lan with names starting with teja e.g tejanag, tejamedha etc are the slaves, so that hadoop master can discover all such names matching the pattern provided through netbios discovery etc.. If the IP address is provided instead of name, say 192.168.0.* then master can run through all the 1 to 255 and discover the slaves. It would be nice to eliminate too much configuration by design or at make configuration more expressive for less changes.
