-------------------------------------

             Summary: mapreduce.user.classpath.first incompatibility with 0.20/1.x
                 Key: MAPREDUCE-4521
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-4521
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: mrv2
    Affects Versions: 2.0.0-alpha, 0.23.1
            Reporter: Jason Lowe


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.
