> 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.
