> 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" on their stderr. Clearly
this depends on HADOOP-975.
