Sergey Shelukhin updated HIVE-20219: ------------------------------------ Description: Discovered while adding tests in HIVE-20029 Step 1. Have a table with fully correct stats. Step 2. Run some query that sets stats to invalid. Step 3. Run analyze without for columns... Result is that while only basic stats are updated, the flag is set to true with old column stats values. I blame json. Not sure if this would affect master, I'll add a test; ACID stats invalidation definitely needs to invalidate all the stats, not just basic stats flag, when invalidating. was: Step 1.
