> This is a follow up Jira for HIVE-22248. For partitioned tables the
> statistics aggregation happens at in the *ColumnStatsAggregator classes
> instead of the *ColumnStatsMerger classes, and they still fail to handle the
> unset low values correctly. Beside that they need to be fixed the two classes
> should use the same codes for merging statistics.
