You really should show your Spark code then. I think you are mistaking
one of the Spark APIs, and are processing a collection of 1
ArrayBuffer at some point, not an ArrayBuffer.

Hi,
I have the following ArrayBuffer:
*ArrayBuffer(5,3,1,4)*
Now, I want to get the number of elements in this ArrayBuffer and also the
first element of the ArrayBuffer. I used .length and .size but they are
returning 1 instead of 4.
I also used .head and .last for getting the first and the last
Hi Deep,
Please find below results of ArrayBuffer in scala REPL
scala import scala.collection.mutable.ArrayBuffer
import scala.collection.mutable.ArrayBuffer
scala val a = ArrayBuffer(5,3,1,4)
a: scala.collection.mutable.ArrayBuffer[Int] = ArrayBuffer(5, 3, 1, 4)
scala a.head
res2: Int = 5
I have a problem here.
When I run the commands that Rajesh has suggested in Scala REPL, they work
fine. But, I want to work in a Spark code, where I need to find the number
of elements in an ArrayBuffer. In Spark code, these things are not working.
How should I do that?
