--action=index --input=/tmp/IMDB-F.arff --output=/tmp/solr --solrconf=./src/main/resources/solr/
Run your classification:
java -Xmx512m -Dfile.encoding=UTF-8 -jar target/knn-classifier-1.0-SNAPSHOT-jar-with-dependencies.jar \
--action=knn --input=/tmp/IMDB-F.arff --output=/tmp/solr --solrconf=./src/main/resources/solr/
