Steve Yeom commented on HIVE-19820:
-----------------------------------
[~sershe] I did not check much details yet but I think the current testTxnTable
and testTxnPartitions at the test module
uses 0 as txnId but txnId is starting from 1.
Also noticed that the way they check and get transactional stats may not be the
way to do.I will try more specifics.
> add ACID stats support to background stats updater

> 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.
