[jira] [Commented] (HIVE-12180) Use MapJoinDesc::isHybridHashJoin() instead of the HiveConf lookup in Vectorizer

    [ https://issues.apache.org/jira/browse/HIVE-12180?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14957873#comment-14957873 ] 

Wei Zheng commented on HIVE-12180:
----------------------------------

The reason for doing this is that there are cases Hybrid is on in HiveConf, but turned off later on based on some conditions.
