Hello. I'm using Nutch 1.3. I decided to upgrade Solr to version 4.0 and I replaced Nutch libs (Snapshot and SolrJ) from Solr dist. After that I got the error at SolrIndexer on Reduce stage:
11/04/19 01:47:19 INFO mapred.JobClient: map 100% reduce 27% 11/04/19 01:47:21 INFO mapred.JobClient: Task Id : attempt_201104190142_0009_r_000000_0, Status : FAILED org.apache.solr.common.SolrException: ERROR: [doc=http://www.site.net/] Error adding field 'tstamp'='2011-04-18T22:45:17.404Z' ERROR: [doc=http://www.site.net/] Error adding field 'tstamp'='2011-04-18T22:45:17.404Z' request: http://127.0.0.1:8983/solr/update?wt=javabin&version=2 at org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:436) at org.apache.solr.client.solrj.impl.CommonsHttpSolrServer.request(CommonsHttpSolrServer.java:245) at org.apache.solr.client.solrj.request.AbstractUpdateRequest.process(AbstractUpdateRequest.java:105) at org.apache.solr.client.solrj.SolrServer.add(SolrServer.java:50) at org.apache.nutch.indexer.solr.SolrWriter.close(SolrWriter.java:75) at org.apache.nutch.indexer.IndexerOutputFormat$1.close(IndexerOutputFormat.java:48) at org.apache.hadoop.mapred.ReduceTask.runOldReducer(ReduceTask.java:474) at org.apache.hadoop.mapred.ReduceTask.run(ReduceTask.java:411) at org.apache.hadoop.mapred.Child.main(Child.java:170) I tried to remove tstamp from solrindex-mapping.xml and Solr's schema.xml. But this field is required in schema.xml and I got the error: 11/04/19 01:58:03 INFO mapred.JobClient: Task Id : attempt_201104190142_0010_r_000000_0, Status : FAILED org.apache.solr.common.SolrException: ERROR: [doc=http://www.site.net/] unknown field 'tstamp' ERROR: [doc=http://www.site.net/] unknown field 'tstamp' How I can upgrade Solr to 4 version? Thank you.
