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

@ Nitin Power, I don't how to put Task Tracker in debug mode.

JDK VERSION - using "java -version" command
------------------------------------------------
java version "1.6.0"
Java(TM) SE Runtime Environment (build 1.6.0-b105)
Java HotSpot(TM) Client VM (build 1.6.0-b105, mixed mode, sharing)

@ Robert Molina,
doing "ls /home/usr/student/pg/yr11/dibyendu_karmakar/hadoop-1.0.3/temp/mapred/local"
gives a directory named "taskTracker"
But this directory is empty --- no file found after doing "ls" on this directory

AND ALSO MY < hadoop.tmp.dir > IS
/home/usr/student/pg/yr11/dibyendu_karmakar/hadoop-1.0.3/temp
