how to merge two tables in hive
As I'm new to Hive I always ended up with a lot of problems,
I want to join two tables and create a single partitioned table based on the country column.
select * from mergetable limit 5;
OK
148.113.13.214 United States
4.175.198.160 United States
24.146.153.181 United States
203.156.137.68 Thailand
114.127.210.217 Indonesia
show create table mergetable;
OK
`CREATE TABLE `mergetable`(
`ipaddrss` string,
`country` string)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY 't'
LINES TERMINATED BY 'n'
STORED AS INPUTFORMAT;`
CREATE TABLE `mergetable1`(
`website` string,
`dt` string,
`tm` string)
ROW FORMAT DELIMITED
FIELDS TERMINATED BY 't'
LINES TERMINATED BY 'n'
STORED AS INPUTFORMAT
hive
