Hi, guys,
Do you see the following error after installing elasticsearch-river-solr
plugin?
{
```
_index: _river
_type: solr_river
_id: _status
_version: 2
_score: 1
_source: {
error: ComputationException[java.
```
lang.NoClassDefFoundError:
org/apache/solr/client/solrj/impl/HttpSolrServer]; nested:
NoClassDefFoundError[org/apache/solr/client/solrj/impl/HttpSolrServer];
nested:
ClassNotFoundException[org.apache.solr.client.solrj.impl.HttpSolrServer];
node: {
id: DrXysOwdRfuRFdFt9GELlQ
name: Asmodeus
transport\_address: inet[/127.0.0.1:9300]
}
}
}
I double checked solr-solrj-3.6.1.jar is there under
elasticsearch-0.20.4/plugins/river-solr and the file contains the class.
Thanks,

Did you restart ES after installing the plugin?
