hive - Sum col2 of two tables based on duplicate matching col1 -


i have 2 tables both structured (id, views)

table 1: id  views   1 b   2 b   3 c   3 c   4 d   4  table 2: id  views c   1 d   3 d   4 e   5 e   7 f   8 

i'm looking sum views of ids both in table 1 , 2 (id c , d) in case output be:

table 3: id  views c   8 d   11 

you use following query in case :

select a.id,sum(a.views) ( select * table1 union table2 ) group id;
