    Description

      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.
