>             Project: Hive
>          Issue Type: New Feature
>          Components: HiveServer2, Security
>    Affects Versions: 4.0.0-alpha-2
>            Reporter: Sai Hemanth Gantasala
>            Assignee: Sai Hemanth Gantasala
>            Priority: Major

> When Hive is using Ranger/Sentry as an authorization service, consider the following scenario.
> {code:java}
> > create table test_udf(st string);   // privileged user operation 
> > create function Udf_UPPER as 'openkb.hive.udf.MyUpper' using jar 'hdfs:///tmp/MyUpperUDF-1.0.0.jar'; // privileged user operation
> > create view v1_udf as select udf_upper(st) from test_udf; // privileged user operation
> //unprivileged user test_user is given select permissions on view v1_udf
> > select * from v1_udf;  {code}
> It is expected that test_user needs to have select privilege on v1_udf and select permissions on udf_upper custom UDF in order to do a select query on view. 
> This patch introduces a configuration "hive.security.authorization.functions.in.view"=false which disables authorization on views associated with views/tables during the select query. In this mode, only UDFs explicitly stated in the query would still be authorized as it is currently.
> The reason for making these custom UDFs associated with view/tables authorizable is that currently, test_user will need to be granted select permissions on the custom udf. and the test_user can use this UDF and query against any other table, which is a security concern.
