Subject [jira] Commented: (HADOOP-673) the task execution environment should have a current working directory that is task specific

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 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.
