Jun Zhang updated FLINK-9444:
-----------------------------
Description:
When some Avro schema has map fields and the corresponding TableSchema declares
*MapTypeInfo* for these fields, an exception will be thrown when registering
the *KafkaAvroTableSource*, complaining like:
Exception in thread "main" org.apache.flink.table.api.ValidationException: Type
Map<String, String> of table field 'event' does not match with type
GenericType<java.util.Map> of the field 'event' of the TableSource return type.
