> Query fails with HiveAccessControlException against table when there is
> Materialized view pointing to that table which end user does not have access
> to, but the actual table user has all the privileges.
> From the HiveServer2 logs - it looks as part of optimization Hive uses
> materialized view to query the data instead of table and since end user does
> not have access on MV we receive HiveAccessControlException.
> https://github.com/apache/hive/blob/master/ql/src/java/org/apache/hadoop/hive/ql/optimizer/calcite/cost/HiveVolcanoPlanner.java#L99
> The Simplest reproducer for this issue is as below.
> 1. Create a table using hive user and insert some data
> {code:java}
> create table db1.testmvtable(id int, name string) partitioned by(year int);
> insert into db1.testmvtable partition(year=2020) values(1,'Name1');
> insert into db1.testmvtable partition(year=2020) values(1,'Name2');
> insert into db1.testmvtable partition(year=2016) values(1,'Name1');
> insert into db1.testmvtable partition(year=2016) values(1,'Name2');
> {code}
> 2. Create Materialized view on top of above table with partitioned and where
> clause as hive user.
> {code:java}
> CREATE MATERIALIZED VIEW db2.testmv PARTITIONED ON(year) as select * from
> db1.testmvtable tmv where year >= 2018;
> {code}
> 3. Grant all (Select to be minimum) access to user 'chiran' via Ranger on
> database db1.
> 4. Run select on base table db1.testmvtable as 'chiran' with where clause
> having partition value >=2018, it runs into HiveAccessControlException on
> db2.testmv
> {code:java}
> eg:- (select * from db1.testmvtable where year=2020;)
> 0: jdbc:hive2://node2> select * from db1.testmvtable where year=2020;
> Error: Error while compiling statement: FAILED: HiveAccessControlException
> Permission denied: user [chiran] does not have [SELECT] privilege on
> [db2/testmv/*] (state=42000,code=40000)
> {code}
> 5. This works when partition column is not in MV
> {code:java}
> 0: jdbc:hive2://node2> select * from db1.testmvtable where year=2016;
