------------------------------------
Summary: Improve details on ModelException when the feature of a
model has not been defined
Key: SOLR-12676
URL: https://issues.apache.org/jira/browse/SOLR-12676
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Components: contrib - LTR
Reporter: Steven Spasbo
While trying to create a model definition, I was getting back the response:
{code}
{
"responseHeader":{
[...]
"error":{
[...]
"msg":"org.apache.solr.ltr.model.ModelException: Model type does not exist
org.apache.solr.ltr.model.LinearModel",
"code":400}
}
}
{code}
I initially thought this was related to the library, but after a while figured
out that I had forgotten to create a feature in my feature store. After
creating that the model was created as expected.
To recreate this:
{code}
curl -XPOST -H 'Content-Type: application/json' \
-d '{
"store" : "myStore",
"name" : "myModel",
"class" : "org.apache.solr.ltr.model.LinearModel",
"features" : [{
"name" : "nonExistentFeature"
}],
"params" : {
"nonExistentFeature" : 1.0
}
}' http://localhost:8983/solr/$CORE/schema/model-store
{code}
