Hi:
These is a problem when I using HIVE. I ran a sql like this:
‘select a, count(*), count(distinct...) from ... group by a ‘
The results when is different when I set hive.groupby.skewindata=True and hive.groupby.skewindata=False. I saw other users also meet this problem.
Is there any way to solve this problem? Or are there any plan to fix this bug?
THANKS !
