Andrew Purtell commented on HBASE-8692:
---------------------------------------
bq. It seems this patch causes calling list on the CLI to no longer work.
It works if the shell is authenticated as a principal with admin privilege.
bq. Will this be enforced on the admin page as well?
No, because the page is rendered by the HBase daemon running under the service
account, which is given superuser privilege. It's expected the UIs are
protected since they leak other sensitive information.
bq. So it's ok to list the table names but not get the descriptors? Should we
add a separate api in HMaster to provide this service then?
The requirement we had was to protect the descriptors. An expansive reading
would include the table names, but I have no opinion here. A separate API for
that sounds good to me.

> 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.
