URL: https://github.com/apache/hive/pull/811
This is a follow up Jira for HIVE-22248Link. 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.
