[jira] Created: (NUTCH-284) NullPointerException during index

NullPointerException during index
---------------------------------

         Key: NUTCH-284
         URL: http://issues.apache.org/jira/browse/NUTCH-284
     Project: Nutch
        Type: Bug

  Components: indexer  
    Versions: 0.8-dev    
    Reporter: Stefan Neufeind


For  quite a few this "reduce > sort" has been going on. Then it fails. What could be wrong with this?

----------------------------------------

Please try discuss such things first in the user mailing list than open a issue. 
Maintaining the issue tracking is very time consuming. But if there is a bug please continue open bug reports. :)
Thanks.

Marko Bauhardt commented on NUTCH-284:
--------------------------------------

I think the index-basic plugin is not included? Because
Line 111: .... doc.getField("url").stringValue() ....

The BasicIndexingFilter index the field "url".

 Verify your Logfile or the nutch-default.xml (or nutch-site.xml).

Stefan Neufeind commented on NUTCH-284:
---------------------------------------

Yes, I was missing index-basic. Please apologize. I needed the extra fields of index-more and thought it would do the basic fields as well.
The same thing occured in NUTCH-51.

Would it be possible to maybe demand that index-basic is loaded (same like "well, you need a scoring-plugin" etc.)? What if somebody writes his own index-basic2-plugin - then he'd have to be able to put an "provides index-basic" into his plugin to notify that he indexes the basic fields or so. Maybe something like this could avoid trouble / searching for some people like me :-)

----------------------------------

I just had somthing similar.

Try the following:

run ant on each of your tasktrackers machines:

% ant

than restart your nutch and try again.

I think there is a problem with the classpath
