> When some Avro schema has map/array fields and the corresponding TableSchema
> declares *MapTypeInfo/ListTypeInfo* 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, Integer> of table field 'event' does not match with type
> GenericType<java.util.Map> of the field 'event' of the TableSource return
> type.
