Siddharth Seth commented on TEZ-3303:
-------------------------------------
[~ozawa] - I don't think the patch actually makes use of the stats. It needs to
check which stats are set - and use that set appropriately. If I'm not mistaken
the current patch only checks and reads detailed stats, but does nothing with
them. cc [~mingma] - in case you'd like to review the patch when it's updated.
> Have ShuffleVertexManager consume more precise partition stats
