    Description

      spark-sql> INSERT INTO t2 VALUES ('1', 'b12345');
      Time taken: 0.141 seconds
      spark-sql> alter table t set location '/tmp/hive_one/t2';
      Time taken: 0.095 seconds
      spark-sql> select * from t;
      1 b1234
      1 a
      1 b

      the above case should fail rather than implicitly applying truncation
