Can you ping any URL successfully? Try www.google.com, www.yahoo.com or something like that.
If you can't ping any of those then you are probably behind a firewall and you'll have to poke a hole into it to get to the outside world. Or you can download the jar that it is trying to find (ivy-2.2.0.jar) from another computer and copy it to the one you are building on. I would put it in this folder : /usr/local/hadoop/pig/new/trunk/ivy/ --Joey On Thu, Dec 29, 2011 at 11:41 PM, praveenesh kumar <praveen...@gmail.com> wrote: > When I am pinging its saying "Unknown
