Hadoop Job Submission

Hi,

I have some rudimentary question.

In order to use Hadoop (both HDFS and MapReduce) does each user whoever wants to run the job needs to start their jobtracker and datanode and submit the job.



Or



is it possible to start the jobtracker and datanode using the user "hadoop" and other users can able to submit the jobs. If this is possible what configuration changes needs to be done so that other users won't get permission error.

Thanks,

Senthil
