• depends upon: HADOOP-801 job tracker should keep a log of task completion and failure
• depends upon: HADOOP-804 Cut down on the "mumbling" in the Task process' stdout/stderr
• is blocked by: HADOOP-975 Separation of user tasks' stdout and stderr streams

• is duplicated by: HADOOP-440 In streaming, error messages issued in stream mappers or reducers don't go anywhere
