   @jinchengchenghh You can reproduce this issue with below SQL.
   ```
   CREATE TABLE htmp1_wide (c1 DECIMAL(38, 18), c2 INT, c3 TIMESTAMP) STORED AS 
ORC;
   INSERT INTO htmp1_wide
   SELECT cast(id AS decimal(38,18)),
          id % 3,
          cast(id % 9 AS TIMESTAMP)
   FROM range(1, 101);
   CREATE TABLE htmp1 (c1 DECIMAL(20, 0), c2 INT, c3 TIMESTAMP) STORED AS ORC 
LOCATION 'hdfs://.../htmp1_wide';
   
   CREATE TABLE htmp2_wide (c1 DECIMAL(38, 18), c2 INT, c3 TIMESTAMP) STORED AS 
ORC;
   INSERT INTO htmp2_wide
   SELECT cast(id AS decimal(38,18)),
          id % 3,
          cast(id % 5 AS TIMESTAMP)
   FROM range(1, 101);
   CREATE TABLE htmp2 (c1 DECIMAL(20, 0), c2 INT, c3 TIMESTAMP) STORED AS ORC 
LOCATION 'hdfs://.../htmp2_wide';
   
   set spark.gluten.sql.columnar.forceShuffledHashJoin=false;
   set spark.gluten.sql.columnar.shuffledHashJoin=false;
   SELECT /*+ MERGE(htmp1) */ htmp1.c2 AS 1c2, htmp1.c3 AS 1c3, htmp2.c2 AS 2c2 
FROM htmp1 JOIN htmp2 ON htmp1.c1 = htmp2.c1;
   ```
