Subject [jira] [Commented] (HIVE-13213) make DbLockManger work for non-acid resources
Date Mon, 07 Mar 2016 20:02:40 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13213?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15183595#comment-15183595

Alan Gates commented on HIVE-13213:
-----------------------------------

Well, not necessarily.  As it stands now non-ACID readers get read committed consistency.
 So you're arguing that both acid and non-acid tables should have the same consistency model.
 I need to think about that.  It's not obvious to me whether that should be true or not.
