This is because the new fields will not be present in older records and hence cannot be populated directly on reading records from existing data. The following field type changes are allowed: old_type ->. new_type int long int float int double long double float double bytes string string bytes Code references: https://github.com/apache/hudi/pull/2350/files https://github.com/rdblue/avro-java/blob/master/avro/src/main/java/org/apache/avro/SchemaCompatibility.java#L359 ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
