Hi,
How to make the query result like the hyperlink lists as Nutch 1.2 did
in Nutch-1.3+solr frame ?
I followed the instruction from
http://wiki.apache.org/nutch/RunningNutchAndSolr ,
After inputting the command,
some error messages like this:
SolrIndexer: starting at 2011-07-23 20:02:04
java.io.IOException: Job failed!
