Hi,
I just check out the latest svn version (376446), I built it from
scratch.
When I tried to run the jobtrucker I got the next message in the
jobtracker log file:
060209 164707 Property 'sun.cpu.isalist' is

060209 164707 Server handler 9 on 50020: starting
Next thing I did is copy the build directory under hadoop path into
the nutch path,
and I didn't get any Exception.
nutch/conf also misses hadoop_default and mapred_default.
Thanks,
Rafit
