             Summary: Move non-type specific column statistics to ColumnStatistics object in ORC
                 Key: HIVE-5787
                 URL: https://issues.apache.org/jira/browse/HIVE-5787
             Project: Hive
          Issue Type: Improvement
    Affects Versions: 0.13.0
            Reporter: Prasanth J
            Priority: Minor


Non-type statistics like min, max, numNulls etc. can be moved to ColumnStatistics class. This avoids ugly checks like 
{code} if (index instanceof IntegerColumnStatistics) {
        return ((IntegerColumnStatistics) index).getMinimum();
      } else if (index instanceof DoubleColumnStatistics) {
        return ((DoubleColumnStatistics) index).getMinimum();
      } else if (index instanceof StringColumnStatistics) {
        return ((StringColumnStatistics) index).getMinimum();
{code}
