Dan Brown commented on SPARK-7460:
----------------------------------
+1 for supporting {{DataFrame.zip}} as a standard operation. I ran into a
pretty weird {{RDD.zip}}/{{DataFrame.withColumn}} bug trying to build it myself:
- https://issues.apache.org/jira/browse/SPARK-10685
> Provide DataFrame.zip (analog of RDD.zip) to merge two data frames
> ------------------------------------------------------------------
