Zoltan Haindrich commented on HIVE-17375:
-----------------------------------------

[~leftylev] Its a somewhat uncommon corner case in which it behaved differently - ( if the
group had only 1 element )
I think we haven't noted the correction of bugs like this earlier...but if you think it would
be better to note it; then I can add a note in the wiki about it! :)

NULL to be returned
