Subject [jira] [Commented] (HIVE-19867) Test and verify Concurrent INSERTS
Date Mon, 18 Jun 2018 17:28:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-19867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16516053#comment-16516053

Steve Yeom commented on HIVE-19867:
-----------------------------------

I found the patch 03 does not address the cases of concurrent writes to a table. 
If writeId for transactional stats is saved into TBLS/PARTITIONS, then 
it can be used to figure out concurrent writes by comparing a write with its writeIdList.
Simply by checking it is in the list or not.
