Need help on Hadoop Map Reduce

Hi,

      I am implementing MapReduce application. For that firstly I am running Wordcount
program. But when I run the program, I am getting the following error :

*java.io.FileNotFoundException: /home/hadoop/pgm/jobTokenPassword (Permission denied)*

The*jobTokenPassword*file is present at that location and it is created with 400 permission
when I run the program . I searched over the internet, but I am not getting the solution
on this problem.

     Please, help to solve this problem.

Hi,

Moving this to mapreduce-user@. We use mapreduce-dev@ only for MR
project development related questions, not user-oriented ones.

What version of Hadoop are you using? And what user are you running
your MR program as (via hadoop jar?).
