Description
dHere is a use case. They have a base table t1, from which they create a view v1. They further create a view v2 from v1 by applying a filter. User has access to only view v2, not view v1 or table t1. When user tries to access v2, they are denied access.
Steps to recreate:
There is a base table t1 that exists in the default database with primary key id and some employee data (name, ssn etc)
Create view v1 - “create view v1 as select * from default.t1;”
Created v2 - “create view v2 as select * from v1 where id =1;”
Permissions provided for user to select all columns from view v2. When user runs select * from v2, hive throws an error “user does not have permissions to select view v1".
Apparently Hive is converting the query to underlying views.
SELECT * FROM v2 LIMIT 100
To
select `v1`.`id`, `v1`.`name`, `v1`.`ssn`, `v1`.`join_date`, `v1`.`location` from `hr`.`v1` where `v1`.`id`=1
Hive should only check for permissions for the view being run in the query, not any parent views. (This is consistent with ORACLE).
