Re: How do specify certain IP to be used by datanode/namenode
Hi J-D, I could not try it right now as I am not familiar with setting up DNS server (I assume the parameters you mentioned are those specifying DNS server). It actually becomes more interesting as why specifying the IP does not suffice? Do you mean that hadoop will decide the right IP of a node by its own, instead of sticking to the default one? -Kevin On Fri, Sep 5, 2008 at 8:45 PM, Jean-Daniel Cryans [EMAIL PROTECTED] wrote: Kevin, Did you try changing the dfs.datanode.dns.interface/dfs.datanode.dns.nameserver/mapred.tasktracker.dns.interface/mapred.tasktracker.dns.nameserver parameters?

Does anyone have an idea how I could possibly make it work? Thank you! -Kevin
