Review Comment:
@mihaibudiu Thanks for the reminder, I had test about it and currently it
not support convert in nested type(such as array),as follow:
**select cast(array[1.0, 2.1, 3.3] as real array) —> SELECT CAST(ARRAY (1.0,
2.1, 3.3) AS REAL ARRAY)**
but not only Hive other systems dialect also not support nested type now, I
would plan to file a new issue and PR to resolve for nested type support. This
pr is just handle with unnested type, WDYT?
