console streams.

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.
