      Description

      All maps had been completed successfully. I had only one reduce task during which
      TaskTracker infinitely outputs:

      07/05/15 19:35:41 INFO mapred.TaskTracker: task_0001_r_000000_0 0.16666667% reduce > copy (4 of 8 at 0.00 MB/s) >
      07/05/15 19:35:42 INFO mapred.TaskTracker: task_0001_r_000000_0 0.16666667% reduce > copy (4 of 8 at 0.00 MB/s) >
      07/05/15 19:35:43 INFO mapred.TaskTracker: task_0001_r_000000_0 0.16666667% reduce > copy (4 of 8 at 0.00 MB/s) >

      JobTracker does not log anything about task task_0001_r_000000_0 except for
      07/05/15 19:49:01 INFO mapred.JobTracker: Adding task 'task_0001_r_000000_0' to tip tip_0001_r_000000, for tracker 'tracker_my-host.com:50050'
