> Carry over encryption table property to derived tables

> Key: HIVE-21849
> URL: https://issues.apache.org/jira/browse/HIVE-21849
> Project: Hive
> Issue Type: Task
> Components: HiveServer2
> Affects Versions: 3.0.1
> Reporter: Xinli Shang
> Assignee: Xinli Shang
> Priority: Major
> Fix For: 3.0.1
>
>
> HIVE-21848 proposed to have a set of table properties to configure the ORC
> and Parquet encryption. In the scenario of CTLT and CTAS, the new table needs
> to have the same encryption table properties because they have the same type
> of sensitive data.
> Furthermore, in the situation like 'insert into', if the source table has
> encrypted sensitive data but the destination doesn't have corresponding table
> property to define the encryption, then destination table will keep it as
> plaintext and hence leaks sensitive data.
> The fix is to carry over table properties for those selected columns from the
> source table to the destination table.
> The code change is working as a prototype. I will share it out later after
> HIVE-21848 has an agreement in the community.
