Subject [jira] [Commented] (HIVE-15323) allow the user to turn off reduce-side SMB join

    [ https://issues.apache.org/jira/browse/HIVE-15323?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15713051#comment-15713051

Gunther Hagleitner commented on HIVE-15323:
-------------------------------------------

LGTM +1. Couple of comments though (since you're resurrecting code, probably fine): a) There
are some checks for whether optraits are null. Other places don't, not sure that's just an
oversight. b) If the group by's parent doesn't have an optraits object we init the # reduce
sinks to 0. That means it will pass the new check, but likely shouldn't...
