navis requested code review of "HIVE-4365 [jira] wrong result in left semi
join".
Reviewers: JIRA
HIVE-4365 wrong result in left semi join
wrong result in left semi join while hive.optimize.ppd=true
for example:
1、create table
create table t1(c1 int,c2 int, c3 int, c4 int, c5 double,c6 int,c7 string)
row format DELIMITED FIELDS TERMINATED BY '|';
create table t2(c1 int) ;
2、load data
load data local inpath '/home/test/t1.txt' OVERWRITE into table t1;
load data local inpath '/home/test/t2.txt' OVERWRITE into table t2;
t1 data:
1|3|10003|52|781.96|555|201203
1|3|10003|39|782.96|555|201203
1|3|10003|87|783.96|555|201203
2|5|10004|24|789.96|555|201203
2|5|10004|58|788.96|555|201203
t2 data:
555
3、excute Query
select t1.c1,t1.c2,t1.c3,t1.c4,t1.c5,t1.c6,t1.c7 from t1 left semi join t2 on
t1.c6 = t2.c1 and t1.c1 = '1' and t1.c7 = '201203' ;
can got result.
select t1.c1,t1.c2,t1.c3,t1.c4,t1.c5,t1.c6,t1.c7 from t1 left semi join t2 on
t1.c6 = t2.c1 where t1.c1 = '1' and t1.c7 = '201203' ;
can't got result.
