[jira] [Commented] (SPARK-7724) Add support for Intersect and Except in Catalyst DSL

    [ https://issues.apache.org/jira/browse/SPARK-7724?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14553059#comment-14553059 ] 

Santiago M. Mola commented on SPARK-7724:
-----------------------------------------

DataFrame is beyond the scope here. I do use the catalyst DSL quite intensively for writing test cases, so I thought that a trivial patch to complete the API would make sense. I can continue using Intersect and Except clases directly though.

> Catalyst DSL to create logical plans supports most of the current plan, but it is missing Except and Intersect. See LogicalPlanFunctions:
