Hi Divya,
You could call *collect()* method provided by DataFram API. This will give
you an *Array[Rows]*. You could then iterate over this array and create
your map. Something like this :
val mapOfVals = scala.collection.mutable.Map[String,String]()
var rows = DataFrame.collect()
rows.foreach(r
Hi,
