                 Key: HADOOP-977
                 URL: https://issues.apache.org/jira/browse/HADOOP-977
             Project: Hadoop
          Issue Type: Improvement
          Components: mapred
    Affects Versions: 0.11.0
            Reporter: Owen O'Malley
         Assigned To: Arun C Murthy
             Fix For: 0.12.0


Currently, the JobClient prints the combined stdout & stderr to the console. It would
be good if the output were tagged with the task id and sent to the stdout or stderr matching
where it was sent by the task. So if your Mapper (task_0001_m_000123_0) writes "foobar" to
stderr, the submitting user would see "task_0001_m_000123_0: foobar". Clearly this depends
on HADOOP-975.
