> Discovered while adding tests in HIVE-20029
> Step 1. Have a table with fully correct txn stats.
> Step 2. Run some query that sets stats to invalid (e.g. parallel inserts).
> 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; if stats state was stored in proper places this kind of bug would be very unlikely.
> 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.
