>                 Key: HIVE-4887
>                 URL: https://issues.apache.org/jira/browse/HIVE-4887
>             Project: Hive
>          Issue Type: Sub-task
>          Components: Authorization, Security
>            Reporter: Thejas M Nair
>
> Hive's RDBMS style of authorization (using grant/revoke), relies on all data access being done through hive select queries. But hive also supports running dfs commands, shell commands (eg "!cat file"), and shell commands through hive streaming.
> This creates problems in securing a hive server using this authorization model. UDF is another way to write custom code that can compromise security, but you can control that by restricting access to users to be only through jdbc connection to hive server (2).
> (note that there are other major problems such as this one - HIVE-3271)
