-----------------------------
[~vikram.dixit] I've forgot whole context of SMBJoin. Could I get some test
queries to follow up your description?
> SMB joins produce incorrect results with multiple partitions and buckets

> Components: Query Processor
> Affects Versions: 0.13.0

>
> It looks like there is an issue with re-using the output object array in the
> select operator. When we read rows of the non-big tables, we hold on to the
> output object in the priority queue. This causes hive to produce incorrect
> results because all the elements in the priority queue refer to the same
> object and the join happens on only one of the buckets.
> {noformat}
> output[i] = eval[i].evaluate(row);
> {noformat}
