Justin Boseant commented on HIVE-4046:
--------------------------------------
The problem with using authorization is that querying one of these columns is
going to result in an error / failed query. The requested functionality
requires that we succeed the query and mask the data.

> Issue Type: New Feature

> Affects Versions: 0.11.0

> Sometimes data in a table needs to be kept around but made inaccessible.
> Right now it is possible to offline a table or a partition, but not a
> specific column of a partition. Also, accessing an offlined table results in
> an error. With this change, it will be possible to mask a column at the
> partition level, causing all further queries to that column to return null.
