The latest svn version is not stable

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
Exception in thread "main" java.lang.NullPointerException
        at 
org.apache.hadoop.mapred.JobTrackerInfoServer.<init>(JobTrackerInfoServer.java:56)
        at org.apache.hadoop.mapred.JobTracker.<init>(JobTracker.java:303)
        at 
org.apache.hadoop.mapred.JobTracker.startTracker(JobTracker.java:50)
        at org.apache.hadoop.mapred.JobTracker.main(JobTracker.java:813)
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

Okay.  I think I just fixed this.  Please give it a try.

Thanks,

Hi Rafit,

The problem is that 'webapps' isn't in the classpath.  If the webapps 
dir gets put under the classpath it fixes that problem.

Thats what I did to fix that problem anyways....

(ie dropping webapps into the build directory)

Jeff.
