Description

set hive.mapred.mode=strict;
drop table mpt3;
create table mpt3 (s1 string , s2 string) partitioned by (dt string, time string);
alter table mpt3 add partition (dt='1',time='2');
drop table mpt4;
create table mpt4 (s1 string , s2 string) partitioned by (dt string, time string);
alter table mpt4 add partition (dt='1',time='2');

Query One: works well
explain
select * from mpt3 a join mpt4 b on (a.s1 = b.s1) where a.dt='1' and a.time='2' and b.dt='1';

Query Two :failed
hive (default)> explain select a.* from mpt3 a right outer join mpt4 b on (a.s1 = b.s1) where a.dt='1' and a.time='2' and b.dt='1';
FAILED: SemanticException [Error 10041]: No partition predicate found for Alias "a" Table "mpt3"

Query Three: failed
hive (default)> explain select a.* from mpt3 a left outer join mpt4 b on (a.s1 = b.s1) where a.dt='1' and a.time='2' and b.dt='1';
FAILED: SemanticException [Error 10041]: No partition predicate found for Alias "b" Table "mpt4"
