Dick King commented on HADOOP-673:
----------------------------------
If you create links from the task-specific directory to the
per-job-directory files and make the task-specific directory you'll
avoid breaking existing code. This assumes people don't write in the
per-job-directory but it's tough to do that in a principled manner so
I wouldn't expect that to happen.
the task execution environment should have a current working
directory that is task specific

Key: HADOOP-673
URL: http://issues.apache.org/jira/browse/HADOOP-673
Project: Hadoop
Issue Type: Bug
Components: mapred
Affects Versions: 0.7.2
Reporter: Owen O'Malley
Assigned To: Owen O'Malley
Fix For: 0.9.0
The tasks should be run in a work directory that is specific to a
single task. In particular, I'd suggest using the
<local>/jobcache/<jobid>/<taskid> as the current working directory.
