> HADOOP-4490 tracks the design and implementation of launching tasks as job owners. As
per discussion there, the proposal is to implement a setuid executable for Linux that would
be launched by the tasktracker to run tasks as the job owners. In this task we will track
the implementation of the setuid executable. HADOOP-4490 will be used to track changes in
the tasktracker.
