Solr Indexing using Nutch Crawler

I'm using Apache Nutch-1.13 and solr 6.6.0 versions.

I'm running the following command to crawl the content:

bin/crawl -i -D solr.server.url=http://localhost:8983/solr/nutch urls/seed.txt TestCrawl 2

I got this exception:

Indexer: java.io.IOException: Job failed!

    at org.apache.hadoop.util.ToolRunner.run(ToolRunner.java:70)

Error running:

Failed with exit value 255.

And in the logs:

Can someone please help me? Thanks in advance.

Solution

In this cases is usually a good idea to check the logs on the Solr side, but for this particular error. You already have the answer, especially the portion:

ERROR: [doc=http://www.cmo.com/features/articles/2017/8/21/5-emerging-technologies-rewrite-the-media-and-entertainment-script-.html] unknown field 'sp_type'
at org.apache.solr.client.solrj.impl.HttpSolrClient.executeMethod(HttpSolrClient.java:576)
at org.apache.solr.client.solrj.impl.HttpSolrClient.request(HttpSolrClient.java:240)

Solr, is complaining that you're sending a document (with id http://www.cmo.com/features/articles/2017/8/21/5...) with one field that is not defined in the schema: sp_type.

You should check what you're sending in that field, or just add the field in the Solr schema.

Keep in mind that if you have more fields that are not defined in the Solr schema, this error will continue to appear. Is usually a good idea to run the bin/nutch indexchecker <URL> command to see what Nutch is going to send to Solr.
