Prasanth J commented on HIVE-8689:
----------------------------------
[~sershe] HIVE-8671 committed now. Can you rebase this patch now? Also can you
fix Mostafa's change to reducer estimation. It will estimate one reducer less
than the previous code. For example: if totalInputFileSize is 140 and
bytesPerReducer is 100 then current change will just say 1 reducer. We should
either have Math.ceil or Math.max(totalInputFileSize, totalInputFileSize +
bytesPerReducer - 1)/bytesPerReducer..
> handle overflows in statistics better
