    Description

      I have seen a reducer in RUNNING state, when it was waiting for the commitResponse.
      Task logs show :
      2009-02-12 08:35:36,414 INFO org.apache.hadoop.mapred.TaskRunner: Task:attempt_200902120746_0297_r_000033_0 is done. And is in the process of commiting
      and no logs after that.
      TT logs say:
      2009-02-12 08:35:36,417 INFO org.apache.hadoop.mapred.TaskTracker: Task attempt_200902120746_0297_r_000033_0 is in COMMIT_PENDING
      2009-02-12 08:35:36,417 INFO org.apache.hadoop.mapred.TaskTracker: attempt_200902120746_0297_r_000033_0 0.33333334% reduce > sort

      This looks like, the task progress went from COMMIT_PENDING to RUNNING again.
