[SPARK-17863] [SQL] should not add column into Distinct #15489
What changes were proposed in this pull request?
We are trying to resolve the attribute in sort by pulling up some column for grandchild into child, but that's wrong when the child is Distinct, because the added column will change the behavior of Distinct, we should not do that.
How was this patch tested?
Added regression test.
