Enis Soztutar commented on HBASE-12511:
---------------------------------------

bq. The current code requires global permission 'CREATE'. However, there is a 
bug in 'requireGlobalPermission' which checks NS permissions
It seems serious, but I lack the history for this. Maybe [~apurtell] can shine 
some light. I thought it is intentional. 

It seems that we should really modify the TestAccessController to test ALL 
combinations in https://hbase.apache.org/book/appendix_acl_matrix.html. Right 
now that test does not do any NS checks AFAIK. 

> namespace permissions - add support from table creation privilege in a 
> namespace 'C'

> As discussed in namespace permission Jira. A user granted a 'C' on a 
> namespace enables a user to create tables within the namespace. 'C' on a 
> namespace does not enable a user to create/drop the namespace.
