----------------------------------
Resolution: Duplicate
> The result of the test case mapjoin1.q is not correct
> ------------------------------------------------------
>
> Key: HIVE-1722
> URL: https://issues.apache.org/jira/browse/HIVE-1722
> Project: 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
