[jira] [Created] (SPARK-33316) Support nullable Avro schemas for non-nullable data in Avro writing

Bo Zhang created SPARK-33316:
--------------------------------

             Summary: Support nullable Avro schemas for non-nullable data in Avro writing
                 Key: SPARK-33316
                 URL: https://issues.apache.org/jira/browse/SPARK-33316
             Project: Spark
          Issue Type: Improvement
          Components: SQL
    Affects Versions: 3.0.1, 3.0.0, 2.4.0
            Reporter: Bo Zhang


Currently when users try to use nullable Avro schemas for non-nullable data in Avro writing, Spark will throw a IncompatibleSchemaException.

There are some cases when users do not have full control over the nullability of the data, or the nullability of the Avro schemas they have to use. We should support nullable Avro schemas for non-nullable data in Avro writing for better usability.
