Subject: JobTracker security

Hi all,

Is there a way to restrict job monitoring and management only to jobs started by each individual user?
The basic scenario is:

1. Start a job under user1
2. Login as user2
3. hadoop job -list to retrieve job id
4. hadoop job -kill job_id
5. Job gets terminated....

Is there something that needs to be enabled to prevent that from happening?

Thanks
Serge
