[jira] [Created] (HIVE-22310) Factor out common code from *ColumnStatsAggregator

Jesus Camacho Rodriguez created HIVE-22310:
----------------------------------------------

             Summary: Factor out common code from *ColumnStatsAggregator
                 Key: HIVE-22310
                 URL: https://issues.apache.org/jira/browse/HIVE-22310
             Project: Hive
          Issue Type: Bug
          Components: Statistics
            Reporter: Jesus Camacho Rodriguez


There are different column stats aggregator instances for each different types, e.g., {{DateColumnStatsAggregator}}, {{LongColumnStatsAggregator}}, {{DoubleColumnStatsAggregator}}, etc. Much of the logic in those classes seems to be common or could be generalized and reused; we should move it into {{ColumnStatsAggregator}} parent class or a utility class.
