> 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.
