Access by name in "tuples" in Scala with Spark

[rzykov <rz...@gmail.com>]

Could you advise the  best practice of using some "named tuples" in Scala
with Spark RDD.
Currently we can access by a field number in a tuple:

RDD.map{_.2}

But want to see such construction:

RDD.map{_.itemId}

This one will be helpful for debugging purposes.

I think you are simply looking for a case class in Scala. It is a
simple way to define an object with named, typed fields.
