Harsh, I have 2 files for jobtracker with extension log and out. Here are both files. There is an error message in out file. Please check both of them and see if you can guide me in this. here are the pastebin links for both files. I also want to mention that with same jave setup I can run hadoop 0.20 successfully but cant configure hadoop 1.0
