Sergey Shelukhin commented on HIVE-19820:
-----------------------------------------
Adds support and tests for various alter table operations for txn stats.
The failing tests above are mostly due to issues with:
1) Conversion to MM (no write ID yet it calls update stats for some reason).
2) Temporary tables (didn't look at specific problem yet).
3) Some NPE in alter (need to look at changes to code paths)
> add ACID stats support to background stats updater and fix bunch of edge
> cases found in SU tests

> Follow-up from HIVE-19418.
> Right now it checks whether stats are valid in an old-fashioned way... and
> also gets ACID state, and discards it without using.
> When ACID stats are implemented, ACID state needs to be used to do
> version-aware valid stats checks.
