>             Project: Ranger
>          Issue Type: Bug
>          Components: plugins
>    Affects Versions: 3.0.0, 2.3.0, 2.4.0
>            Reporter: kirby zhou
>            Priority: Major
>
> In agents-common/src/test/resources/policyengine/test_policyengine_hive.json,
> we have hive policy:
> {code:java}
> {"id":8,"name":"db=dummy; table=*; column=*","isEnabled":true,"isAuditEnabled":true,
> "resources":{"database":{"values":["dummy"]},"table":{"values":["*"]},"column":{"values":["*"]}},
> "policyItems":[
> {"accesses":[{"type":"create","isAllowed":true},{"type":"update","isAllowed":true},{"type":"drop","isAllowed":true}],"users":["user1","user2"],"groups":[],"delegateAdmin":false}
> ],
> "allowExceptions":[
> {"accesses":[{"type":"create","isAllowed":true}, {"type":"update","isAllowed":true}],"users":["user1"],"groups":[],"delegateAdmin":false},
> {"accesses":[{"type":"create","isAllowed":true}, {"type":"update","isAllowed":true},{"type":"drop","isAllowed":true}],"users":["user2"],"groups":[],"delegateAdmin":false}
> ]
> } {code}
> According to the general understanding, this is given the permission of column level, rather than the permission of table level or database level.
>  
> But these 2 new test case can pass:
> {code:java}
> {"name":"ALLOW 'drop dummy/*;' for user1",
>   "request":{
>     "resource":{"elements":{"database":"dummy", "table": "dummy"}},
>     "accessType":"drop","user":"user1","userGroups":["users"],"requestData":"drop dummy/dummy for user1"
>   },
>   "result":{"isAudited":true,"isAllowed":true,"policyId":8}
> }
> ,
> {"name":"ALLOW 'drop dummy;' for user1",
>   "request":{
>     "resource":{"elements":{"database":"dummy"}},
>     "accessType":"drop","user":"user1","userGroups":["users"],"requestData":"drop dummy for user1"
>   },
>   "result":{"isAudited":true,"isAllowed":true,"policyId":8}
> }
>  {code}
>  
> This doesn't seem reasonable.
> Or can someone tell me how to only give users column-level permissions without involving table or database?
