[ http://issues.apache.org/jira/browse/HADOOP-673?page=all ]
Doug Cutting updated HADOOP-673:
--------------------------------
Status: Open (was: Patch Available)
This patch changes fullyDelete() to run 'rm -rf'. We should only rely on unix
command-line tools when we absolutely must, and I don't think we have to here.
Instead, before listing a directory, we should compare getAbsoluteFile() to
getCanonicalFile() to determine whether it's a symbolic link. If it is a
symbolic link, then we should ignore it.
Also, perhaps most of the code added to TaskRunner could be instead added to
DistributedCache, since it's cache-specific stuff?
> the task execution environment should have a current working directory that
> is task specific

> 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.
