Thank you! This is what I needed, I've read it should work as the first()
method as well. It's a pity that the taken element cannot be removed from
the RDD though.
Thanks again!

You can rdd.take(1) to get just the header line.
I think someone mentioned before that this is a good use case for
having a tail method on RDDs too, to skip the header for subsequent
processing. But you can ignore it with a filter, or logic in your map
method.

Hi everyone!
I'm really new to Spark and I'm trying to figure out which would be the
proper way to do the following:
1.- Read a file header (a single line)
2.- Build with it a configuration object
3.- Use that object in a function that will be called by map()
I thought about using filter() after textFile(), but I don't want to get
an
RDD as result for I'm expecting a unique object.
Any help is very appreciated.
Thanks in advance,
Silvina
