             Summary: Provide an option to skip stats generation for major compaction
                 Key: HIVE-23536
                 URL: https://issues.apache.org/jira/browse/HIVE-23536
             Project: Hive
          Issue Type: Improvement
          Components: Transactions
            Reporter: Peter Vary
            Assignee: Peter Vary


Currently major MR compaction is regenerates stats every time if the column stats table contains some data. Some configurations do not use stats but because of historical reasons the column stats table can still contain some data.
We should provide a possibility to skip stats generation in these cases.
