      Description

      Timestamps in the future (year 2250?) and before ~1700 are silently corrupted in vectorized execution mode. Simple repro:

      hive> DROP TABLE IF EXISTS test;
      hive> CREATE TABLE test(ts TIMESTAMP) STORED AS ORC;
      hive> INSERT INTO TABLE test VALUES ('9999-12-31 23:59:59');
      
      hive> SET hive.vectorized.execution.enabled = false;
      hive> SELECT MAX(ts) FROM test;
      9999-12-31 23:59:59
      
      hive> SET hive.vectorized.execution.enabled = true;
      hive> SELECT MAX(ts) FROM test;
