I have a multicore implementation of solr. I want to configure DIH / core. I manage to make it work on single core solr. What I assume, I have to make the configurations / core, which means I create the data-import.xml in the core’s conf directory and rewrite solrconfig.xml of the core. I also copied in the lib the maching driver for dih, but I get an error message:
org.apache.solr.common.SolrException: Error loading class

Any clue, what I’m doing wrong? Thanks in advance.
The dataimporthandler isn’t included anymore in the solr.war. You should add the jar
apache-solr-dataimporthandler-x.x.x.jar(please replace the x.x.x with your current version) to your classpath. You can find it in the dist folder of the solr zip file you’ve downloaded.
