Summary: query form a view join another view happens "No work
found for tablescan TS"
Key: TEZ-3541
URL: https://issues.apache.org/jira/browse/TEZ-3541
Project: Apache Tez
Issue Type: Bug
Affects Versions: 0.8.4
Environment: hive2.1.0
Tez0.8.4
hadoop2.7.2
Reporter: gaoyang
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???
