Re: Task Tracker Not Starting in Hadoop-1.0.3 Help Please
I see. Could you please post your JT logs? Also, comment out "127.0.1.1" in
your "/etc/hosts" and try to restart the cluster. I am assuming rest of the
things are working fine.

(I am sorry as I am not able to post any direct answer, as it's very
difficult to diagnose the actual problem without error logs).

Regards,
