----------------------------
Summary: ClusteringComponent added using Config API causes error
when reloading the collection
Key: SOLR-9354
URL: https://issues.apache.org/jira/browse/SOLR-9354
Project: Solr
Issue Type: Sub-task
Components: config-api, contrib - Clustering
Affects Versions: 6.0.1
Environment: SolrCloud on Windows with ZooKeeper 3.4.8
Reporter: Alex D
It is not possible to add a clustering search component when using the Config
API.
Command I used to add the clustering component:
curl -k -u admin:admin https://solrserver:8443/solr/customer/config -H
'Content-type:application/json' -d '{ "add-searchcomponent":
{"name":"clustering", "class":"solr.clustering.ClusteringComponent","engine":[{
"name":"lingo",
"carrot.algorithm":"org.carrot2.clustering.lingo.LingoClusteringAlgorithm"}, {
"name":"stc",
"carrot.algorithm":"org.carrot2.clustering.stc.STCClusteringAlgorithm"}]} }'
Error I received from the curl command:
{
"responseHeader":{
"status":500,
"QTime":30026},
"errorMessages":["1 out of 2 the property overlay to be of version 7 within
30 seconds! Failed cores:

the future.",

In my Solr logs I can see the following error related to the clustering
component:
Caused by: java.lang.ClassCastException: java.util.ArrayList cannot be cast to
org.apache.solr.common.util.NamedList
at
org.apache.solr.handler.clustering.ClusteringComponent.inform(ClusteringComponent.java:110)
at
org.apache.solr.core.SolrResourceLoader.inform(SolrResourceLoader.java:675)
at org.apache.solr.core.SolrCore.<init>(SolrCore.java:751)
I should mention that I do not get any errors if I specify only one clustering
engine instead of a list of engines.
