What You Expected?

works good enough.

How to Reproduce?

CREATE TABLE left_outer_left_table ( k1varchar(200) NULL COMMENT "" ) ENGINE=OLAP UNIQUE KEY(k1) COMMENT "olap" DISTRIBUTED BY HASH(k1) BUCKETS 20 PROPERTIES ( "in_memory" = "false", "storage_format" = "V2", "replication_num" = "1" );

CREATE TABLE left_outer_right_table ( k2varchar(100) NULL COMMENT "" ) ENGINE=OLAP UNIQUE KEY(k2) COMMENT "olap" DISTRIBUTED BY HASH(k2) BUCKETS 20 PROPERTIES ( "in_memory" = "false", "storage_format" = "V2", "replication_num" = "1" );

explain select k2 from left_outer_left_table a left outer join left_outer_right_table b on b.k2 = a.k1 where a.k1='uuid'
