> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: tasktracker
> Reporter: Vinod K V
> Assignee: Amareshwari Sriramadasu

> To enforce the accessibility of job files to only the job-owner and the
> TaskTracker, as per MAPREDUCE-842, it is _trusted_ that the setuid/setgid
> linux TaskController binary is group owned by a _special group_ to which only
> TaskTracker belongs and not just any group to which TT belongs. If the trust
> is broken, possibly due to misconfiguration by admins, the local files become
> accessible to unintended users, yet giving false sense of security to the
> admins.
