> HADOOP-2838 and HADOOP-5981 added support to make the TaskTracker's shell environment available to the tasks. This has two problems:
>   1. It makes the task tracker's environment part of the interface to the task, which is fairly brittle.
>   2. Security code typically only passes along whitelisted environment variables instead of everything to prevent accidental leakage from the administrator's account.
