{type} no abstract type InputDistribution

Error message

{type} no abstract type InputDistribution 

What it means

Velox protocol serialization error: serializing an InputDistribution whose _type discriminator is not '.BaseInputDistribution' (the only known subclass). to_json falls through all recognized branches and throws TypeError, meaning an unknown InputDistribution subclass reached the native protocol layer.

Solutions

1. Ensure only BaseInputDistribution instances are used in native plans
2. Add the missing subclass to the C++ protocol mapping
3. Check for protocol drift between Java and presto_cpp versions
