xiaohang.li updated HIVE-24177:
-------------------------------
Description:
when i use mapjoin,hive throws Execution failed with exit status.
以下是我的测试demo:
CREATE TABLE `fact`(CREATE TABLE `fact`( `id` int, `name` string) ROW
FORMAT SERDE 'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe' WITH
SERDEPROPERTIES ( 'field.delim'='\t', 'serialization.format'='\t') ;
vi fact.txt1 lee2 lee2
load data local inpath 'fact.txt' into table fact;
create table dim_table( id int, name string)ROW FORMAT SERDE
'org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe' WITH SERDEPROPERTIES (
'field.delim'='\t', 'serialization.format'='\t');
vi dim.txt1 lee2 test3 test34 test45 test56 test67 test8 test9 test10 test
load data local inpath 'dim.txt' into table dim_table;
then i create a lowwer udf :
add jar udfdemo-1.0.jar;
create temporary function mylower as 'com.test.hive.Lower';
select *
from(
select id,name,mylower00001(name) user_id
from fact
)t1
join dim_table t2
on t2.name='test';
the error is below:
