@EmmyMiao87 主要感觉问题集中于存在Group by字段没有带dbName； 以及a join b group by b的字段的时候，由于Fragment只存了a表的分布，所以datapartition的表是a而不是b，这个时候无法做优化。 explain select count(1) from (select k1,k2 from test.t1 group by t1.k1,t1.k2) a,t2 b where a.k1 = b.k1 and a.k2 = b.k2 group by b.k1,b.k2; -- This is an automated message from the Apache Git Service.
