### Search before asking - [X] I had searched in the [issues](https://github.com/apache/doris/issues?q=is%3Aissue) and found no similar issues. ### Version nereids planner has this problem, all versions. ### What's Wrong? colocate group keys do not the same as on condition, we should no use colocate join, then make the result do not correctly. ### What You Expected? get correct result ### How to Reproduce? 1. create table a, use k1 as distributed key ``` CREATE TABLE `a` ( `k1` INT NOT NULL, `k2` INT NOT NULL, `v` INT SUM NULL ) ENGINE=OLAP AGGREGATE KEY(`k1`, `k2`) COMMENT 'OLAP' DISTRIBUTED BY HASH(`k1`) BUCKETS 10 PROPERTIES ( "replication_allocation" = "tag.location.default: 1", "colocate_with" = "k1_group" ); ``` 2. create table b, use k2 as distributed key ``` CREATE TABLE `b` ( `k1` INT NOT NULL, `k2` INT NOT NULL, `v` INT SUM NULL ) ENGINE=OLAP AGGREGATE KEY(`k1`, `k2`) COMMENT 'OLAP' DISTRIBUTED BY HASH(`k2`) BUCKETS 10 PROPERTIES ( "replication_allocation" = "tag.location.default: 1", "colocate_with" = "k1_group" ); ``` 3. and table a and b use the same colocate group: `k1_group` 4. add some data to table and table b ``` insert into a values(1,2,3); insert into b values(1,2,3); ``` 5. check the planner, we found colocate join is used. Actually in this case, we should not use colocate join: ``` explain select * from a join b on a.k1=b.k1 and a.k2=b.k2; ``` ### Anything Else? _No response_ ### Are you willing to submit PR? - [X] Yes I am willing to submit a PR! ### Code of Conduct - [X] I agree to follow this project's [Code of Conduct](https://www.apache.org/foundation/policies/conduct) -- This is an automated message from the Apache Git Service.
