Andrew Purtell updated HBASE-8692:
----------------------------------
Release Note: This change adds support for restricting access to table
schema. Only a user with GLOBAL ADMIN privilege can enumerate the full list of
table schemas. If passed a list of specific tables, the AccessController will
check that the user has either GLOBAL ADMIN privs, or TABLE ADMIN or TABLE
CREATE privs for all of the listed tables before allowing the request.
Got a +1 on RB. Updated release notes. Going to commit to trunk and 0.94 after
running the full unit test suite.
> [AccessController] Restrict HTableDescriptor enumeration

> Key: HBASE-8692
> URL: https://issues.apache.org/jira/browse/HBASE-8692
> Project: HBase
> Issue Type: Improvement
> Components: Coprocessors, security
> Affects Versions: 0.98.0, 0.95.1, 0.94.9
> Reporter: Andrew Purtell
> Assignee: Andrew Purtell
> Attachments: 8692-0.94.patch, 8692.patch

>
> Some users are concerned about having table schema exposed to every user and
> would like it protected, similar to the rest of the admin operations for
> schema.
> This used to be hopeless because META would leak HTableDescriptors in
> HRegionInfo, but that is no longer the case in 0.94+.
> Consider adding CP hooks in the master for intercepting
> HMasterInterface#getHTableDescriptors and
> HMasterInterface#getHTableDescriptors(List<String>). Add support in the
> AccessController for only allowing GLOBAL ADMIN to the first method. Add
> support in the AccessController for allowing access to the descriptors for
> the table names in the list of the second method only if the user has TABLE
> ADMIN privilege for all of the listed table names.
> Then, fix the code in HBaseAdmin (and elsewhere) that expects to be able to
> enumerate all table descriptors e.g. in deleteTable. A TABLE ADMIN can delete
> a table but won’t have GLOBAL ADMIN privilege to enumerate the total list. So
> a minor fixup is needed here, and in other places like this which make the
> same assumption.
