      Description

      Single partition works, but multiple partitions will not work.
      Reproduce steps:

      DROP TABLE IF EXISTS t1;
      DROP TABLE IF EXISTS t2;
      DROP TABLE IF EXISTS t3;
      DROP TABLE IF EXISTS t4;
      
      CREATE TABLE t1 (a int) PARTITIONED BY (d1 int);
      CREATE TABLE t2 (a int) PARTITIONED BY (d1 int);
      CREATE TABLE t3 (a int) PARTITIONED BY (d1 int, d2 int);
      CREATE TABLE t4 (a int) PARTITIONED BY (d1 int, d2 int);
      
      INSERT OVERWRITE TABLE t1 PARTITION (d1 = 1) SELECT salary FROM jsmall LIMIT 10;
      INSERT OVERWRITE TABLE t3 PARTITION (d1 = 1, d2 = 1) SELECT salary FROM jsmall LIMIT 10;
      
      SELECT * FROM t1;
      
      SELECT * FROM t3;
      
      ALTER TABLE t2 EXCHANGE PARTITION (d1 = 1) WITH TABLE t1;
      SELECT * FROM t1;
      SELECT * FROM t2;
      
      ALTER TABLE t4 EXCHANGE PARTITION (d1 = 1, d2 = 1) WITH TABLE t3;
      SELECT * FROM t3;
      SELECT * FROM t4;
      

      The output:

      0: jdbc:hive2://10.17.74.148:10000/default> SELECT * FROM t3;
      +-------+--------+--------+--+
      | t3.a  | t3.d1  | t3.d2  |

      0: jdbc:hive2://10.17.74.148:10000/default> SELECT * FROM t4;
