Subject [jira] Updated: (HADOOP-673) the task execution environment should have a current working directory that is task specific
Date Tue, 05 Dec 2006 05:55:24 GMT
     [ http://issues.apache.org/jira/browse/HADOOP-673?page=all ]

Mahadev konar updated HADOOP-673:
---------------------------------

    Attachment: cwd.patch

this patch fixes the problem. It implements owens second proposal ie.
1) The current working dir for each task is the task directory
2) for streaming all the contents of job.jar are symlinked into this current working directory
for the tasks.

This patch depends upon HADOOP-748. I have included the patch for HADOOP-748 in this patch.

> 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.
