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

             Summary: Min value for column in stats is not set correctly for some data types in partitioned tables
                 Key: HIVE-22328
                 URL: https://issues.apache.org/jira/browse/HIVE-22328
             Project: Hive
          Issue Type: Bug
            Reporter: Miklos Gergely
            Assignee: Miklos Gergely


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.
