[jira] [Commented] (HIVE-8932) Enable n-way join on CBO

    [ https://issues.apache.org/jira/browse/HIVE-8932?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14220305#comment-14220305 ] 

Ashutosh Chauhan commented on HIVE-8932:
----------------------------------------

An attempt for this was made in HIVE-8558 but in other cases we still fail to do n-way joins e.g., {{join12.q,ppd_join3.q,ppd_outer_join4.q}}
