Zac Zhou updated HIVE-18270:
----------------------------
Description:
When I run the following query:
explain
SELECT foo.id, count(distinct foo.line_id) as factor from
foo JOIN bar ON (foo.id = bar.id)
WHERE foo.orders != 'blah'
group by foo.id;
The following error is got:

It looks like it is a bug of ReduceSinkDeDuplication optimizer.
Since the columns of count distinct need to be added into reduce key for
sorting, the reducesink of group can't be replaced with the ones of join.
In the case of count distinct query, reducesink of group should not be merged
