The TaskTracker's shell environment should not be passed to the children.

                 Key: HADOOP-6058
                 URL: https://issues.apache.org/jira/browse/HADOOP-6058
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
            Reporter: Owen O'Malley
            Priority: Critical
             Fix For: 0.21.0


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.
