When creating a view in Hive that includes an Atlas tagged column, why is the view not restricted by the same policy as it's source table?

When I have a table in Atlas which blocks a user from selecting on the ssn column of table1, I create a view (view1) which has ssn as a column and then I am able to select * on view1 with the user that would have been denied select * on table1.

Is there a way to ensure that all downstream tables / views cary the same policy as their parent?

Or is this the expected and desired behavior?

@Vasilis Vagias - In the case of a CTAS operation in hive, tags in Atlas that are associated with the source entities (columns, tables, views etc.) are not propagated to resulting entities in Atlas. This is mostly a function of Atlas not currently providing column level lineage. Both column level lineage as well as tag propagation are roadmap items.

In short, the behavior that you are seeing is expected.

@Erik Bergenholtz any guess on the release date with this feature ?

Update: The tag propagation feature (ATLAS-1821) was released as part of HDP 3.0.0.
