Description

Here is my sql:
select count(0) from tbllog_level_up b,tbllog_gold a where b.server=a.server and b.role_id=a.role_id;
tbllog_level_up and tbllog_gold is view which union by two tables, like this:
create view tbllog_level_up as select * from tbllog_level_up_current union all select * tbllog_level_up_bak;
create view tbllog_gold as select * from tbllog_gold_current union all select * tbllog_gold_bak;
When i run the sql on hive2.1 with mr engine，it is ok.
But it throws the following exception with Tez0.8.4 engine:

In addition，when i change the sql like this：select count(0) from tbllog_gold b,tbllog_level_up a where b.server=a.server and b.role_id=a.role_id
It will succeed.
Why???
