Sourabh Badhya updated HIVE-27421:
----------------------------------
Description:
Non-native table formats like Iceberg has the capability to store column stats
in its own format (for Iceberg: Its stored in Puffin files).
However, these stats are stored in metastore as well after setting the column
stats in its own format. We must avoid setting column stats in 2 places and
must set only in a single place.
