Ah. *headdesk* So this means the Solr Server is required for the Plugin to be called. Ok. That was not the case when I tried Nutch the last time (probably one year or more ago). At that time a Lucene Index was used and I assumed this would still be the case if no Solr Server is configured. I'll try this. Thanks for the answer to both of you.

Hi Klemens,

as Lewis stated:

Unless you are indexing nothing will happen. You specify an indexing
filter so you actually need to index something before the filter is
run.
Although it is loaded this doesn't mean that anything is being indexed.


If you run the indexer and there are documents to index you should see
something like this:

2012-07-06 23:26:12,917 INFO solr.SolrIndexer - SolrIndexer: starting at 2012-07-06 23:26:12
...
2012-07-06 23:26:55,075 INFO indexer.IndexingFilters - Adding myPlugin
...
<myPlugin log messages>
...
2012-07-06 23:26:55,176 INFO solr.SolrWriter - Indexing 12 documents
2012-07-06 23:27:00,798 INFO solr.SolrIndexer - SolrIndexer: finished at 2012-07-06 23:27:00,
elapsed: 00:00:47

Alternatively, to be faster, try
nutch indexchecker <url>
and watch the hadoop.log

Hi,

I am trying to create a very simple Nutch plugin that simply prints something to the command line or hadoop.log during execution. I followed the tutorial on setting up Nutch in Eclipse from the Wiki and also the Tutorial on creating a simple Plugin. I also found another Tutorial here: http://florianhartl.com/nutch-plugin-tutorial.html#comment-41 and followed that as well.

After some problems I finally managed to get Nutch up and running and my Plugin to be registered
according to hadoop.log

2012-08-12 21:36:48,578 INFO plugin.PluginRepository - Add Field to Index (myPlugin)

However, regardless of what I am attempting I seem to be unable to make the plugin actually run. It seems to not be executed. There was a guy having the same problem in the comments of the second tutorial I followed and since I am developing under Linux it might be possible that my problem is
related to the following:
http://lucene.472066.n3.nabble.com/Nutch-plugin-ignored-in-linux-works-on-windows-td3191884.html

However none of these questions got an answer up to now? So has there been some new insight on running custom plugins under Linux (actually Ubuntu 12.04) or could it be something completely
different? Any ideas?

I would absolutely willing to provide you with additional information if you could tell me what you
need.

Regards
