Tianhan Hu created SPARK-38574:
----------------------------------

             Summary: Enrich Avro data source documentation
                 Key: SPARK-38574
                 URL: https://issues.apache.org/jira/browse/SPARK-38574
             Project: Spark
          Issue Type: Improvement
          Components: Spark Core
    Affects Versions: 3.2.1
            Reporter: Tianhan Hu


Enrich Avro data source documentation to emphasize the difference between 
*avroSchema* which is an option, and *jsonFormatSchema* which is a parameter for function *from_avro* .

When using {*}from_avro{*}, *avroSchema* option can be set to a compatible and evolved schema, while *jsonFormatSchema* has to be the actual schema. Elsewise, the behavior is undefined.
