Subject [jira] [Commented] (HIVE-10807) Invalidate basic stats for insert queries if autogather=false
Date Fri, 29 May 2015 20:27:17 GMT

    [ https://issues.apache.org/jira/browse/HIVE-10807?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14565343#comment-14565343

Gunther Hagleitner commented on HIVE-10807:
-------------------------------------------

Seems straightforward (adding a clear to inserts iff autogather=false), but I don't understand
some of the golden file updates. Could you comment on why these are correct. (cc [~mmokhtar]).
