> In MAPREDUCE-6454 (target for branch-2.x), we provide an extremely fragile
> way 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.
