Hi,everyone
I know “hive.groupby.skewindata“ can be used when there is skew in data,but I

I've tried to make a test.

select platform,count(distinct did) uv from acm_expose_v1 where visit_date =
'2016-11-06' group by platform

Hi,all
we are trying to upgrade Hive Auth Mode. There is something I can’t understand.
why actions like create、drop function can be done by admin only ?
In the default auth mode,everyone can create functions. I can’t see the reasons.
Anyone can explain it? thanks so much
try to configdatanucleus.schema.autoCreateTables=true in hive-site.xml
