Aihua Xu commented on HIVE-16875:
---------------------------------

I see. We are expecting an alias_id here rather than an alias. 

nit: maybe we can change alias to alias_id and the same in the function {{setupMapWork(MapWork mapWork, GenSparkProcContext context, PrunedPartitionList partitions, TableScanOperator root, String alias)}} to be clear.

Otherwise, the change looks good to me. +1.

> Query against view with child table that has partitions fails with privilege exception even with correct privileges.
> Reproduce:
> {noformat}
> create table jsamp1 (a string) partitioned by (b int);
> insert into table jsamp1 partition (b=1) values ("hello");
> create view jview as select * from jsamp1;
> create role viewtester;
> grant all on table jview to role viewtester;
> grant role viewtester to group testers;
> Use MR, the select will succeed:
> set hive.execution.engine=mr;
> select count(*) from jview;
> while use spark:
> set hive.execution.engine=spark;
> select count(*) from jview;
> it fails with:
> Error: Error while compiling statement: FAILED: SemanticException No valid privileges
>  User tester does not have privileges for QUERY
>  The required privileges: Server=server1->Db=default->Table=j1part->action=select; (state=42000,code=40000)
> {noformat}
