The ArrayBuffer did the trick!
Thanks a lot! I'm learning Scala through spark so these details are still new
to me

Hey,
I just reread your question and saw I overlooked some crucial information.
Here's a solution:
val data =
model.asInstanceOf[DistributedLDAModel].topicDistributions.sortByKey().collect()
val tpdist = data.map(doc => doc._2.toArray)
hope it works this time

Hi Daniel,
You're actually not modifying the original array: `array :+ x ` will give
you a new array with `x` appended to it.
In your case the fix is simple: collect() already returns an array, use it
as the assignment value to your val.
In case you ever want to append values iteratively, search
Hello,
I'm trying to put all the values in pair rdd into an array (or list) for later
storing, however even if I'm collecting the data then pushing it to the array
the array size after the run is 0.
Any idea on what I'm missing?
Thanks in advance
