----------------------------------
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.
