The result of the test case mapjoin1.q is not correct
------------------------------------------------------
Key: HIVE-1722
URL: https://issues.apache.org/jira/browse/HIVE-1722
Project: Hadoop Hive
Issue Type: Bug
Components: Query Processor
Affects Versions: 0.6.0, 0.7.0
Reporter: Liyin Tang
Assignee: Liyin Tang
In the test case mapjoin1.q :
SELECT /*+ MAPJOIN(b) */ sum(a.key) as sum_a FROM srcpart a JOIN src b ON
a.key = b.key where a.ds is not null;
The current result in mapjoin1.q.out shows the result is 76260.0
But actually, if user remove the map join hint, and run the query:
SELECT sum(a.key) as sum_a FROM srcpart a JOIN src b ON a.key = b.key where
a.ds is not null;
The result is 1114788.0
And I import these input data into mysql to test, and test result is also
1114788.0.
Obviously, the current result is not correct
