dongjoon-hyun commented on issue #24682: [SPARK-27762][SQL] [FOLLOWUP] Add behavior change for Avro writer in migration guide URL: https://github.com/apache/spark/pull/24682#issuecomment-495054805 I understand the concern about the difference from our default `.schema` option. I believe this is the main reason why we add `.option("avroSchema", ...)`. For Avro, `nullable` column type is `"type": ["int", "null"]` and non-nullable column type is `"type": "int"` explicitly.
