    [ https://issues.apache.org/jira/browse/HIVE-18571?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16381295#comment-16381295 ] 

Sergey Shelukhin commented on HIVE-18571:
-----------------------------------------

The patch is ready for review and I don't expect major changes (other that from CR feedback).
However, I'll wait for HIVE-18824 before committing, so that the code that uses ACID state to get stats would actually work.
It would be the code already in the patch, however currently it bails and sets stats to 0 because write IDs for tables being written are not there.

> There are multiple stats aggregation issues with MM tables.
> Some simple stats are double counted and some stats (simple stats) are invalid for ACID table dirs altogether. 
> I have a patch almost ready, need to fix some more stuff and clean up.
