> 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
