      Description

      It will be useful for allow cluster-admins to set some java options for child map/reduce tasks.

      E.g. We've had to ask users to set -Djava.net.preferIPv4Stack=true in their jobs, it would be nice to do it for all users in such scenarios even when people override mapred.child.

      {map|reduce}

      .java.opts but forget to add this.
