> 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.
