I have a partitioned table on timestamp_dt:
> desc daily_count_per_kg_domain;
OK
ddnamesyskg string
totalcount int
timestamp_dt string
hive> select * from daily_count_per_kg_domain;
OK
sys_kg_band 224 20140219
sys_kg_event 3435 20140219
sys_kg_movies 44987 20140219
sys_kg_oly 4172 20140219
sys_kg_sp_countr 5499 20140219
sys_kg_sports 3954 20140219
sys_kg_tv 21387 20140219
sys_kg_venue 152 20140219
sys_kgathlete 9000 20140219
sys_kgpeople 300064 20140219
Looking to compute percentages for each row, (per day):
100* totalcount / sum(totalcount)
Intuitively i tried :
> select totalcount / sum(totalcount) from daily_count_per_kg_domain
where timestamp_dt = '20140219' ;
FAILED: SemanticException [Error 10025]: Line 1:7 Expression not in
GROUP BY key 'totalcount'
I am not sure what group by on totalcount means..
Any ides ?
