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).

surprising to see that TT is restarting without any error after it checks
for the directory ownership mapred local directories.

can you try putting tasktracker startup in debug mode? (which version of
JDK are you using? )

Hi Dibyendu,
I believe TT is trying to do some cleanup.  What is currently in

/home/usr/student/pg/yr11/dibyendu_karmakar/hadoop-1.0.3/temp/mapred/local

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
@ Mohammad Tariq,

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

@ Robert,
I was trying the same in 172.16.4.14 and it was not running as well.
Tasktracker is not running at all.
I am using hadoop-1.0.3

But yesterday, I tried the old hadoop-0.22.0 and every daemon,
including tasktracker is running quite beautifully....
Actually, I am trying to understand the code for hadoop... so the
purpose is to run the WordCount program given in MapReduce Example...
But I cann't complie this program in hadoop-0.22.0 because
hadoop-core-version.jar is not there in hadoop-0.22.0 whereas it is in
hadoop-1.0.3 and compilation is successful...

THANKS FOR YOUR CONSTANT REPLY..
DON'T KNOW WHAT I'LL DO IN MY PROJECT ON HADOOP.
THANKS AGAIN...
