Subject Re: Task Tracker Not Starting in Hadoop-1.0.3 Help Please
Date Wed, 05 Dec 2012 22:50:14 GMT
Hi Dibyendu,
Looking back at your logs, you are trying to start TT on the 120 box where
your the master processes along with datanode is running.  I was wondering
if you tried to launch TT on the 172.16.4.14 as well and get the same
behavior.

Regards,
Robert
