Issue while enabling clustering/integrating carrot2 with solr
4.4.0 and tomact under ubuntu
1.My solr.xml
<?xml version="1.0" encoding="UTF-8" ?>
<solr persistent="true" sharedLib="/solr/lib">
<cores defaultCoreName="rn0" hostContext="/solr" adminPath="/admin/cores"
hostPort="8980">
<core schema="schema.xml" shard="shard1" instanceDir="rn0/" name="rn0"
config="solrconfig.xml" collection="rn"/>
......
......
</cores>
</solr>
2.My solrconfig.xml changes for carrot2 integrate
<searchComponent
class="org.apache.solr.handler.clustering.ClusteringComponent"
enable="${solr.clustering.enabled:false}" name="clustering">
<lst name="engine">
<str name="name">default</str>
<str
name="carrot.algorithm">org.carrot2.clustering.lingo.LingoClusteringAlgorithm</str>
<str name="LingoClusteringAlgorithm.desiredClusterCountBase">20</str>
</lst>
</searchComponent>
<requestHandler name="/clustering" startup="lazy"
enable="${solr.clustering.enabled:false}" class="solr.SearchHandler">
.....
.....
.....
.....
</requestHandler>
<lib dir="/solr/lib" regex=".*\.jar" />
3.Copied all the required jars to /solr/lib folder those are
solr-clustering-4.4.0.jar
carrot2-mini-3.6.2.jar
hppc-0.4.1.jar
jackson-core-asl-1.7.4.jar
jackson-mapper-asl-1.7.4.jar
mahout-collections-1.0.jar
mahout-math-0.6.jar
simple-xml-2.6.4.jar
4.created a file named setenv.sh under "/usr/share/tomcat/bin/" with
clustering enabled
CATALINA_OPTS = "-Dsolr.clustering.enabled=true"
5.Restarted tomcat and
I am getting the following error while starting solr server after
-Dsolr.clustering.enabled=true on CATALINA_OPTS

Re: Issue while enabling clustering/integrating carrot2 with solr
4.4.0 and tomact under ubuntu
Posted by Erick Erickson <er...@gmail.com>.
Class cast exceptions are usually the result of having a mix of old
and new jars in your classpath, or even of having the same jar in two
different places. Is this possible here?
Best,
Erick
