------------------------------------
Summary: Vectorization problem with empty partition
Key: HIVE-12774
URL: https://issues.apache.org/jira/browse/HIVE-12774
Project: Hive
Issue Type: Bug
Reporter: Lance Norskog
Priority: Minor
A query against a table with no data in partition X fails under vectorization.
Table:
{quote}
use default;
drop table if exists test;
CREATE TABLE default.test(
district_id bigint,
user_type string,
7d int)
PARTITIONED BY
(partition_date string)
ROW FORMAT SERDE
'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe'
STORED AS INPUTFORMAT
'org.apache.hadoop.mapred.TextInputFormat'
OUTPUTFORMAT
'org.apache.hadoop.hive.ql.io.HiveIgnoreKeyTextOutputFormat'
{quote}
Query:
{quote}
set hive.vectorized.execution.enabled = true;
select partition_date, sum(teachers_7d)
from
(
select distinct ad1.partition_date, ad1.district_id, ad1.7d teachers_7d
from default.test ad1
left join default.test ad2 on ad1.district_id = ad2.district_id and
ad2.user_type = 'STUDENT'
and ad2.partition_date = '2015-12-20'
where ad1.user_type = 'TEACHER'
and ad1.partition_date = '2015-12-20'
) a
group by partition_date
;
