Allen Wittenauer updated MAPREDUCE-6458:
----------------------------------------
Description: 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. (was: In MAPREDUCE-6454 (target for
