      Description

      For non-partitioned tables, Hive-generated statistics are stored in table properties. However, for partitioned tables, Hive-generated statistics are stored in partition properties. Thus, we are unable to utilize the Hive-generated statistics for partitioned tables.

      The statistics might not be gathered for all the partitions in Hive. For partial collection, we will not utilize the Hive-generated statistics.
