The SOLR connector is a high speed mechanism for writing data to Apache Solr.
If you are seeing error messages such as Invalid version (expected 2, but 60) or the data in not in ‘javabin’ format compare the version of the Solr Server against the version of solrj the connector is compiled with. This error message is most likely due to a version mismatch between the server and solrj. To address this try replacing the solr-solrj-*.jar packaged with the connector with the version that matches the Solr server you are connecting to.
