Subject [jira] Updated: (HADOOP-673) the task execution environment should have a current working directory that is task specific
Date Thu, 07 Dec 2006 23:44:29 GMT
     [ http://issues.apache.org/jira/browse/HADOOP-673?page=all ]

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

    Attachment: cwd_1.patch

This patch uses java for deleteting the symlinks and have moved the creating of symliks to
DistributedCache. The java code tries deleting a directory first which succeeds if its empty
or a symlink and if it does not succeed it tries deleting the directory recursively. This
works both on cygwin and linux.

> 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.
