org.apache.hadoop.hive.ql.exec.vector.LongColumnVector
This class represents a nullable int column vector. This class will be used for operations on all integer types (tinyint, smallint, int, bigint) and as such will use a 64-bit long value to hold the biggest possible value. During copy-in/copy-out, smaller int types will be converted as needed. This will reduce the amount of code that needs to be generated and also will run fast since the machine operates with 64-bit words. The vector[] field is public by design for high-performance access in the inner loop of query execution.

        reader = inputFormat.getRecordReader(splits[0], conf, Reporter.NULL);

    assertEquals(true, reader.next(key, value));
    assertEquals(10, value.count());
    LongColumnVector col0 = (LongColumnVector) value.cols[0];
    for(int i=0; i < 10; i++) {
      assertEquals("checking " + i, i, col0.vector[i]);
    }
