Description:
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}
