I’m trying to get the BaseClusterIntegrationTest code working inside one of my projects. I’ve solved a few issues, but am now running into the FunctionRegistry’s static{} init code trying to treat org/apache/pinot/core/operator/transform/function/zone-index.properties file as a class file, which obviously fails. No idea why this doesn’t cause problems normally, but seems like the

filterInputsBy()

filter should be set up to only include class files, so this .properties file isn’t picked up. Thoughts?

Yes, the reflection should only pick up the class files. Can you please try replacing the filter string to

".*\\.function\\..*\\.class"

if see if the problem is fixed? If so, can you also file a PR to fix it?
