Has anybody managed to make "clustering" working with Solr in Cloudera Quickstart VM with CHD5?

I get the following error in Solr log:

I changed the Solr configuration to use -Dsolr.clustering.enabled=true in Java Configuration Options forSolrServer (this gets applied to $CATALINA_OPT)

and copied the clustering jar file plus contribs from the parcels to my local lib

cp/opt/cloudera/parcels/CDH-5.0.0-1.cdh5.0.0.p0.47/lib/solr/solr-clustering-4.4.0-cdh5.0.0.jar lib

cp -R /opt/cloudera/parcels/CDH-5.0.0-1.cdh5.0.0.p0.47/share/doc/solr-doc-4.4.0+cdh5.0.0+178/solr-clustering/org/apache/solr/handler/clustering/* lib

then used full path in solrconfig.xml to point to the jar file.

<libpath="/home/cloudera/solr/lib/solr-clustering-4.4.0-cdh5.0.0.jar" />

and restarted solr using CM.

in the meantime I could solve this myself

I copied the carrot2 libs from carrot2-java-api-3.9.3 (both required and optional) into /var/lib/solr/carrot2/lib/

and added followig into solrconfig.xml

After restarting Solr the clustering did work.
