    Description

      Prior to hadoop 0.23, users could add third party jars to the lib subdirectory of the submitted job jar and they become available in the task's classpath. I see this functionality was in TaskRunner.java, but I can't see similar functionality in hadoop 0.23 (neither in MapReduceChildJVM.java nor other places).
