      Description

      This is a tool to reproduce problems and to run unit tests involving either a map or reduce task.
      You just give it a reduce directory on the command line.

      Usage: java org.apache.hadoop.mapred.StandaloneReduceTask <taskdir> [<limitmaps>]
      taskdir name encodes: task_<jobid>r<partition>_<attempt>
      taskdir contains job.xml and one or more input files named: map_<dddd>.out
      You should run with the same -Xmx option as the TaskTracker child JVM
