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. > Column masking > -------------- > > Key: HIVE-4046 > URL: https://issues.apache.org/jira/browse/HIVE-4046 > Project: Hive > Issue Type: New Feature > Components: Authorization, CLI, Metastore, Query Processor, Security > Affects Versions: 0.11.0 > Reporter: Samuel Yuan > Assignee: Samuel Yuan > > 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. -- This message is automatically generated by JIRA.
