> 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.
