Well, the patch consumes the data from a csv. You have to modify the input to use TableInputFormat (I don't remember if it's called exaclty like that) and it will work. Once you've done that, you have to specify as much reducers as shards you want.
I know 2 ways to index using hadoop method 1 (solr-1301 & nutch): -Map: just get data from the source and create key-value -Reduce: does the analysis and index the data So, the index is build on the reducer side method 2 (hadoop lucene index contrib) -Map: does analysis and open indexWriter to add docs -Reducer: Merge small indexs build in the map So, indexs are build on the map side method 2 has no good integration with Solr at the moment. In the jira (SOLR-1301) there's a good explanation of the advantages and disadvantages of indexing on the map or reduce side. I recomend you to read with detail all the comments on the jira to know exactly how it works. -- View this message in context: http://lucene.472066.n3.nabble.com/anyone-use-hadoop-solr-tp485333p914625.html Sent from the Solr - User mailing list archive at Nabble.com.
