-----------------------------
Summary: Hive Ingnoring where clause for multitable insert
Key: HIVE-4173
URL: https://issues.apache.org/jira/browse/HIVE-4173
Project: Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.9.0, 0.8.1
Environment: Red Hat Enterprise Linux Server release 6.3 (Santiago),
Reporter: hussain
Priority: Critical
Hive is ignoring Filter conditions given at Multi Insert select statement when
Filtering given on Source Query..
To highlight this issue, please see below example with where clause
(status!='C') from employee12 table causing issue and due to which insert
filters (batch_id='12 and batch_id!='12' )not working and dumping all the data
coming from source to both the tables.
I have checked the hive execution plan, and didn't find Filter predicates under
for filtering record per insert statements
from
(from employee12
select *
where status!='C') t
insert into table employee1
select
status,
field1,
'T' as field2,
'P' as field3,
'C' as field4
where batch_id='12'
insert into table employee2
select
status,
field1,
'D' as field2,
'P' as field3,
'C' as field4
where batch_id!='12';
It is working fine with single insert. Hive generating plan properly..
I am able to reproduce this issue with 8.1 and 9.0 version of Hive.
