> In insecure clusters, all user code runs as mapred. With our default insecure
> install, the setuid to root linux task controller provides mapred with the
> ability to run processes as any user. The combination of these is bad. I think
> we should separate out the setuid executable to a separate rpm that is only
> installed on secure clusters.
