[ http://issues.apache.org/jira/browse/HADOOP-673?page=comments#action_12455829 ] Doug Cutting commented on HADOOP-673: -------------------------------------
> Can the difference between getAbsoluteFile() and getCanonicalFile() be used > reliably? I think so. The docs for getCanonicalFile() explicitly mention symbolic links, while getAbsoluteFile() is merely supposed to resolve relative paths against CWD. > What happens under cygwin? Cygwin shouldn't impact this, since these are implemented by the JVM. > 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: Mahadev konar > Attachments: cwd.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. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
