Vinod K V updated MAPREDUCE-103:
--------------------------------
Component/s: security
> The TaskTracker's shell environment should not be passed to the children.
> -------------------------------------------------------------------------
>
> Key: MAPREDUCE-103
> URL: https://issues.apache.org/jira/browse/MAPREDUCE-103
> Project: Hadoop Map/Reduce
> Issue Type: Bug
> Components: security
> Reporter: Owen O'Malley
> Priority: Critical
>
> 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.
