Subject [jira] [Commented] (HIVE-16399) create an index for tc_txnid in TXN_COMPONENTS
Date Mon, 01 May 2017 22:47:04 GMT

    [ https://issues.apache.org/jira/browse/HIVE-16399?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15991696#comment-15991696

Wei Zheng commented on HIVE-16399:
----------------------------------

Re-attach patches for branch-2.3, branch-2 and master. At this moment we don't make any change
to branch-2.2 as the details for that release is still on the fly.

[~ekoifman] Can you take another look?
