Subject [jira] [Commented] (HIVE-19820) add ACID stats support to background stats updater
Date Tue, 26 Jun 2018 16:34:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-19820?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16523945#comment-16523945

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.

> 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.
