---------------------------------------
bq. Re-assigning this to me and updating the description to reflect reality,
since I actually understand how bash works.
Please feel free to take it if you have bandwidth to work on it immediately.

> Issue Type: Bug
> Reporter: Junping Du
> Assignee: Allen Wittenauer
>
> 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.
