> Hive desc [formatted|extended] operation cost more than 100 seconds after
> upgrading from Hive 1.2.1 to 2.3.4. This is mainly caused by showing stats
> for partitioned tables which was introduced by HIVE-16098 when the
> partitioned tables have a large amount of partitions. In our case, the number
> of partition is 187221.
