[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=15907632#comment-15907632 ] 

Chang chen commented on SPARK-7460:
-----------------------------------

+1 for supporting {{DataFrame.zip}}, python guys of my company  usually use {{pandas.concat}} for appending columns, so they expect spark has this functionality also.

[~rxin], I just curious why did you say it is hard to get it right? Since there is {{RDD.zip}}, if you are right, then {{RDD.zip}} is also hard to get it right.

> 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)
