hello, [#1972 ](https://github.com/apache/hudi/issues/1972) brought me here. Since, that one has been closed, I want to bring up my question here. Hope someone could help to answer. It seems the conclusion for #1972's solution is to support schema evolution. But, to me, #1972 is more about for the symbol "union" where should the "null" to be presented if any. As for avro 1.9.2, it requires null to be the first schema in union for nullability. Would it be better for the spark team to upgrade their support to avro 1.9.2 ? and then in turn they would change method: toAvroType in SchemaConverters to put nullSchema at the front while creating union? To me, this looks more like a rule breaking rather than schema evolution. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
