             Summary: Figure out the way to pass build-in classpath (files in 
distributed cache, etc.) from parent to spawned shells
                 Key: MAPREDUCE-6458
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6458
             Project: Hadoop Map/Reduce
          Issue Type: Bug
            Reporter: Junping Du
            Assignee: Junping Du


In MAPREDUCE-6454 (target for branch-2.x), we provide a 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 complicatedly pass build-in 
classpath.
