   ### Version
   
   2.1.3
   
   ### What's Wrong?
   
   Given a table with a column that is an aggregate key:
   `CREATE TABLE t1(c0 varchar(1) NOT NULL) AGGREGATE KEY(c0) DISTRIBUTED BY 
RANDOM PROPERTIES ("replication_num" = "1");`
   
   If we insert duplicate entries, and select distinct, we get duplicate rows
   ```
   INSERT INTO t1 (c0) VALUES ('a');
   INSERT INTO t1 (c0) VALUES ('a');
   
   SELECT DISTINCT t1.c0 FROM t1; -- returns both rows
   ```
   
   ### What You Expected?
   
   only distinct rows returned
   
   ### How to Reproduce?
   
   ```
   DROP DATABASE IF EXISTS doris0;
   CREATE DATABASE doris0;
   USE doris0;
   CREATE TABLE t1(c0 varchar(1) NOT NULL) AGGREGATE KEY(c0) DISTRIBUTED BY 
RANDOM PROPERTIES ("replication_num" = "1");
   INSERT INTO t1 (c0) VALUES ('a');
   INSERT INTO t1 (c0) VALUES ('a');
   
   SELECT DISTINCT t1.c0 FROM t1;
   ```
