Re: Task Tracker Not Starting in Hadoop-1.0.3 Help Please
@ 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...
