[jira] [Commented] (SPARK-7460) Provide DataFrame.zip (analog of RDD.zip) to merge two data frames

    [ https://issues.apache.org/jira/browse/SPARK-7460?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14804890#comment-14804890 ] 

Dan Brown commented on SPARK-7460:
----------------------------------

> an analog of RDD1.zip(RDD2) for data frames allows us to merge two data frames without stepping down to the RDD layer and back. (syntactic sugar)
