>             Project: Hadoop Map/Reduce
>          Issue Type: Bug
>            Reporter: Junping Du
>            Assignee: Dustin Cote
>         Attachments: MAPREDUCE-6458.00.patch
> In MAPREDUCE-6454 (target for branch-2.x), we provide a way with constraints 
> to pass built-in classpath from parent to child shell, via HADOOP_CLASSPATH, 
> so jars in distributed cache can still work in child tasks. In trunk, we may 
> think some way different, like: involve additional env var to safely pass 
> build-in classpath.
