      Description

      ReduceTask splits its progress reporting into 3 phases
      1. Copy
      2. Shuffule
      3. Reduce

      When the reduce task is run using a LocalJobRunner, the copy phase is ignored (skipped) but the progress is not updated. This results in a mismatch in the Reduce task's progress.
