Subject [jira] [Commented] (SENTRY-74) Add column-level privileges for Hive/Impala
Date Tue, 11 Nov 2014 03:35:34 GMT


Prasad Mujumdar commented on SENTRY-74:

with latest Hive build, there are a bunch of failures. I have update the SENTRY-509 patch
to fix the tests, we'll commit it once we have a clean run.

Looks like SENTRY-390 patch is not updated on the ticket and RB. Are the review comments addressed
by other changes ?
Other than that, I guess this feature is pretty much ready.

> Currently the finest grain of privilege is at the table/view level. This leads to the
unwieldy scenario where a different view has to be created for each combination of columns
that need to be restricted. With column level privileges this would not be required.
> In the policy file column privileges might potentially look like:
> server=server1->db=default->table=employees->column=salary->action=select
