> 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.
