JIRA is not a good place to ask questions -- please use u...@spark.apache.org.
This is for reporting issues, so I'd recommend closing this.

> someone help me with the above manipulation and how to do that.
> Or may be if there is some way to take the transpose of the data and then
> manipulating the rows in some way?
> Thank you in advance, I am struggling with this thing for quite sometime
