public static Date getRandDate(Random r) {
 String dateStr = String.format("%d-%02d-%02d",
   Integer.valueOf(1800 + r.nextInt(500)),  // year
   Integer.valueOf(1 + r.nextInt(12)),      // month
   Integer.valueOf(1 + r.nextInt(28)));     // day
 Date dateVal = Date.valueOf(dateStr);
 return dateVal;
}

private Object convertLiteral(Object o) {
  // This is a bit hackish to fix mismatch between SARG and Hive types
  // for Timestamp and Date. TODO: Move those types to storage-api.

   return Date.valueOf(o.toString());
  } else if (o instanceof java.sql.Timestamp) {
   return Timestamp.valueOf(o.toString());
  }
