Ashutosh Chauhan commented on HIVE-4197:
----------------------------------------
[~alangates] Stable sort issue seems to be an important one, especially since
because of shuffle enhancements between hadoop1 and hadoop2 sort is not stable
between two for same query. Harish's proposal is to always add filename and
file offset virtual column which I think will enforce stable sort. In absence
of any other solution, this looks like fine to me. Do you think we can do any
better?
