Subject Re: Problem with running hadoop jar demo.jar in local mode.
Date Sat, 23 Jun 2012 09:09:17 GMT
Your local /tmp directory needs to be writable by your user, for the
"hadoop jar" method to execute properly out of the box.

If that is not possible, edit your conf/core-site.xml to change the
"hadoop.tmp.dir" default of "/tmp/hadoop-${user.name}" to somewhere
that is writable by you, perhaps "${user.home}/tmp" for your user
