TopGunViper opened a new pull request #577: HIVE-21485: Add flag to turn off fetching partition stats in DESCRIBE… URL: https://github.com/apache/hive/pull/577 ## What changes were proposed in this pull request? Hive DESCRIBE [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](https://issues.apache.org/jira/browse/HIVE-16098) when the partitioned tables have a large amount of partitions. So，could we add a flag that determines whether 'DESCRIBE [EXTENDED|FORMATTED]' operation display partitioned table stats or not? ## How was this patch tested? Query Unit Test
