    Description

      In Hadoop 0.20 or 1.x, jobs can specify the user's classpath should appear first by setting the property mapreduce.user.classpath.first to true in the job configuration. However in Hadoop 0.23 or 2.x, this has no effect, as the corresponding property there is mapreduce.job.user.classpath.first.
