-------------------------------------------
Summary: Learning To Rank model upload fails generically
Key: SOLR-15149
URL: https://issues.apache.org/jira/browse/SOLR-15149
Project: Solr
Issue Type: Bug
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Alessandro Benedetti
When uploading a model, using a not existent store or other incorrect
parameters you get:
"error":{
"metadata":[
"error-class","org.apache.solr.common.SolrException",
"root-error-class","java.lang.ClassCastException"],
"msg":"org.apache.solr.ltr.model.ModelException: Model type does not exist
org.apache.solr.ltr.model.LinearModel",
"code":400}}
In the response, logs don't help that much out of the box, I had to go for
remote debugging and of course we don't want the generic user to do that.
Reason is in org/apache/solr/ltr/model/LTRScoringModel.java:111
{code:java}
try {
// create an instance of the model
model = solrResourceLoader.newInstance(
className,
LTRScoringModel.class,
new String[0], // no sub packages
new Class[] { String.class, List.class, List.class, String.class,
List.class, Map.class },
new Object[] { name, features, norms, featureStoreName, allFeatures,
params });
if (params != null) {
SolrPluginUtils.invokeSetters(model, params.entrySet());
}
} catch (final Exception e) {
throw new ModelException("Model type does not exist " + className, e);
}
{code}
unless any objection, we should improve such message with the real one
