> Currently, MapReduce uses the command line argument to pass the classpath to
> the child. This breaks if the process forks a child that needs the same
> classpath. Such a case happens in Hive when it uses map-side joins. I propose
> that we make MapReduce in branch-1 use the CLASSPATH environment variable
> like YARN does.
