Description

Consider the following scenario:
2 database in Hive: db1, db2
2 tables, one in each database: db1.tbl1, db2.tbl2
Ranger: add a resource based policy to allow all access to public on db=; tbl=; col=*
Execute ‘show databases;’ via beeline; it lists both db1 and db2
Atlas: add EXPIRES_ON tag to db2.tbl2 with expiry_date 2016/12/31
Ranger: add a tag-based policy to deny all access to public on for EXPIRES_ON tag with access-after-expiry=true
Execute ‘show databases’ via beeline; the user should see ‘db1’. Instead following error is shown:

Error while compiling statement: FAILED: HiveAccessControlException Permission denied: user [admin] does not have [USE] privilege on [null] (state=42000,code=40000)
