[jira] [Commented] (SPARK-2215) Multi-way join

    [ https://issues.apache.org/jira/browse/SPARK-2215?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14187798#comment-14187798 ] 

Reynold Xin commented on SPARK-2215:
------------------------------------

I think a simplified version of the multi-way join would make sense, i.e. one that does multi-way inner-equi-broadcast join.
