Owen O'Malley updated HADOOP-977:
---------------------------------
Description: 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. (was: Currently, the JobClient prints the combined stdout &
