> Key: HIVE-25590

> Project: Hive
> Issue Type: Bug
> Components: Query Planning
> Reporter: Krisztian Kasa

> Creating views/materialized views referencing temporary tables and
> materialized views are disabled in Hive. However the verification algorithm
> fails to recognize temporary tables and materialized views in subqueries.
> The verification also fails when the view definition contains joins because
> CBO transforms join branches to subqueries.
> Example1:
> {code}
> create temporary table tmp1 (c1 string, c2 string);
> create view tmp1_view as
> select subq.c1 from (select c1, c2 from tmp1) subq;
> {code}
> Example2:
> {code}
> create table t1 (a int) stored as orc tblproperties ('transactional'='true');
> create table t2 (a int) stored as orc tblproperties ('transactional'='true');
> create materialized view mv1 as
> select a from t1 where a = 10;
> create materialized view mv2 as
> select t2.a from mv1
> join t2 on (mv1.a = t2.a);
> {code}
