Hi Sami,

I assume the idea is that the JVM knows about hadoop.log.dir system

_always_ work.
That is, when invoking various bin/nutch commands as described in
http://lucene.apache.org/nutch/tutorial8.html , this fails, and the
system attempts to write to "/" which, of course, is a directory,
not a file.
Can you be more precise on this one - what commands do fail? What
kind of configuration are you running this on?
I'll have to look at another server's logs tomorrow, but I can tell
you that the error is much like the one in
http://issues.apache.org/jira/browse/NUTCH-307 :
java.io.FileNotFoundException: / (Is a directory) cr06: at

There is really not much to any kind of particular configuration, it
is just that those properties are unset, so when log4j has to
interpret this:
log4j.appender.DRFA.File=${hadoop.log.dir}/${hadoop.log.file}
It gets interpreted as:
log4j.appender.DRFA.File=/
Because those 2 properties are undefined. And that will happen if you
follow this tutorial: http://lucene.apache.org/nutch/tutorial8.html
This tutorial uses things like inject, generate, fetch, etc., while
the 0.8 tutorial on Wiki does not. When you use the 0.8 tutorial
from the Wiki, the properties do get set somehow, so everything
works. So it's a matter of those properties not getting set.
What I meant by configuration was that are you running on one box and
executing your tasks with LocalJobRunner or do you use one or more boxes
and use TaskTracker to run your jobs?
