Hi Deep,
I believe that you are referring to the map for Iterable[String]
suppose you have
iter:Iterable[String]
you can do
newIter = iter.map(item = Item + a )
which will create an new Iterable[String] with each element appending an
a to all string in iter.
Does this answer your question?

what should come in the map??
Thanks Liquan for answering me...

Hi Deep,
The Iterable trait in scala has methods like map and reduce that you can
use to iterate elements of Iterable[String]. You can also create an
Iterator from the Iterable. For example, suppose you have
val rdd: RDD[Iterable[String]]
you can do
rdd.map { x = //x has type Iterable[String]
x.map(...) // Process elements in iterable[String]
val iter:Iterator[String] = x.iterator
while(iter.hasNext) {
iter.next()
}
}
Hope this helps!

Can we iterate over RDD of Iterable[String]? How do we do that?
Because the entire Iterable[String] seems to be a single element in the
RDD.
Thank You
