      Description

      I just noticed the following curious situation:

      -) 18 of 22 reducers are waiting for 3 hours or so with 0.01MB/s and no progress.
      -) hadoop job -kill-task does not work on the ids shown
      -) killing all reduce work tasks (the spawned Python processes, not java TaskTracker$Child) gets completely ignored by the JobTracker, the jobtracker shows them still as running.
