[jira] [Commented] (HIVE-16092) Generate and use universal mmId instead of per db/table

    [ https://issues.apache.org/jira/browse/HIVE-16092?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15895159#comment-15895159 ] 

Wei Zheng commented on HIVE-16092:
----------------------------------

On a second thought, this may not be a good idea. Keeping the mmId the way it is (per table) is actually beneficial for things like DR. Will need to seek alternatives of integrating ACID txn. [~ekoifman]
