Andrew Purtell commented on HBASE-8692:
---------------------------------------
bq. Yeah sorry that's what I meant as majority of users aren't admins and
"list" to me is one of the first thing users do after opening the CLI. Is that
the intent then? Non-admin users can't list tables?
Yes that is the intent, but it is a side effect of the fact the API used by the
shell retrieves descriptors.
bq. Instead of blocking access why not secure it like the other hadoop admin
pages?
This patch doesn't block access to the UI. We may be talking past each other.
The secure deployment model I use is only admins/operations see the UIs. Is
there a JIRA open for presenting different levels of information on the UI to
users authenticating with different levels of privilege? I haven't seen it.
Should we have one?

> 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.
