Streaming should deliver stderr to the user.
--------------------------------------------
Key: HADOOP-478
URL: http://issues.apache.org/jira/browse/HADOOP-478
Project: Hadoop
Issue Type: Bug
Components: contrib/streaming
Reporter: arkady borkovsky
Streaming should collect stderr output of -mapper and - reduces steps and put
it into the place accessible by the user.
E.g. it can go into
/user/name/stderr/job-id/task-id.txt
This is indpendent from MapReduce framework catching stderr of "normal" Java
MapReduce jobs.
A Java programmer has many ways to handle the problem on her own (at least
until the framework matures and provides more help).
Unlike her, a user of Streaming has no access to files.
Therefore it is an immediate requirement for Streaming to provide its own
support for delivering this critical data to the user.
