Subject [jira] [Commented] (HIVE-18875) Enable SMB Join by default in Tez
Date Tue, 29 May 2018 01:31:00 GMT

    [ https://issues.apache.org/jira/browse/HIVE-18875?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16492992#comment-16492992

Gunther Hagleitner commented on HIVE-18875:
-------------------------------------------

I've also read more of the code in ConvertJoinMapJoin. You've introduced a check that the
column lists are the same right before an existing call to "checkColEquality". That seems
mostly redundant, except that you turned the sort col step from non-strict to strict. Why
is any of this code needed?
