> 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.
