>       There are some issue exist while involving complex data type using Hive dialect in Flink.
>  # It will throw exception when access array type in a struct. For example, such sql will fail:
> {code:java}
> create table t (s6 map<string, struct<f20:array<string>>>);
> SELECT s6['key1'].f20[0] FROM nested_tbl_1;{code}
>       2. Hive supports to access the field of a struct list by '.' , but it'll throw exception using Hive dialect in Flink.
