Sergey Shelukhin commented on HIVE-20219:
-----------------------------------------
The issue is specific to txn stats
> analyze and analyze for columns don't manage stats state correctly
> ------------------------------------------------------------------

> Key: HIVE-20219
> URL: https://issues.apache.org/jira/browse/HIVE-20219
> Project: Hive
> Issue Type: Sub-task
> Reporter: Sergey Shelukhin
> Assignee: Sergey Shelukhin
> Priority: Major
>
> 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.
