{parse_error} InputDistribution InputDistribution

Error message

{parse_error} InputDistribution  InputDistribution

What it means

Velox protocol deserialization error: extracting the subclass key of an InputDistribution from JSON threw a parse error. from_json wraps the json::parse_error with the InputDistribution tag, indicating a malformed serialized input-distribution entry in the plan fragment.

Solutions

1. Verify the serialized JSON contains the expected type field
2. Match Java and native protocol definitions for InputDistribution
3. Re-run without native execution to isolate the protocol mismatch
