writing DStream RDDs to the same file

[Adrian Mocanu]

Hi
Is there a way to write all RDDs in a DStream to the same file?
I tried this and got an empty file. I think it's bc the file is not closed i.e. 
ESMinibatchFunctions.writer.close() executes before the stream is created.

Here's my code
  myStream.foreachRDD(rdd => {
        rdd.foreach(x => {
          ESMinibatchFunctions.writer.append(rdd.collect()(0).toString()+" the 
data ")        })
//        localRdd = localRdd.union(rdd)
//        localArray = localArray ++ rdd.collect()
      } )

ESMinibatchFunctions.writer.close()

object ESMinibatchFunctions {
  val writer = new PrintWriter("c:/delme/exxx.txt")
}
