I have been pulling my hair out on this one. I tried building it within eclipse - no errors, but when I put the jar file in and restart eclipse I can see the Map/Reduce prospective but once I try to do anything it bombs with random cryptic errors. I looked at Stephen's notes on jiva but still no go. I am desperate to get this working so bribes, kick-backs other reciprocity will be gladly considered. ;-) Thanks!
