----------------------------------

             Summary: Column stats should be preserved when it is renamed
                 Key: HIVE-15742
                 URL: https://issues.apache.org/jira/browse/HIVE-15742
             Project: Hive
          Issue Type: Improvement
          Components: Statistics
            Reporter: Chaoyu Tang

Currently, when a column is renamed, its stats is delete. Recreating it could be expensive
and we need preserve it if possible.
