HiveOnTez: mix of union all, distinct, group by generates error
---
Key: HIVE-9141
URL: https://issues.apache.org/jira/browse/HIVE-9141
Project: Hive
Issue Type: Bug
Reporter: Pengcheng Xiong
Assignee: Navis
Attachments: HIVE-9141.1.patch.txt
Here is the way to produce it:
in Hive q test setting (with src table)
set hive.execution.engine=tez;
SELECT key, value FROM
(
SELECT key, value FROM src
UNION ALL
SELECT key, key as value FROM
(
SELECT distinct key FROM (
SELECT key, value FROM
(SELECT key, value FROM src
UNION ALL
SELECT key, value FROM src
)t1
group by key, value
)t2
)t3
)t4
group by key, value;
will generate
