["Steve Yeom (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HIVE-18619?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16351334#comment-16351334 ] 

Steve Yeom commented on HIVE-18619:
-----------------------------------

Note that session based temporary table is only visible to its session. 
Thus there is no possible issues in Concurrency and Isolation.

> Session based temporary table by HIVE-7090 had no consideration of Micromanaged table 
> (MM) since there was no insert-only ACID table at its creation tije. 
> HIVE-18599 addressed the issue of no writes during CTTAS (Create Temporary Table As Select)
> on Micro-Managed table. But atomicity of temporary MM table is not verified.
