Hadoop Iterable

Hi, I am working with Hadoop MapReduce, and am trying to write the kmeans
algorithm (I already know about mahout). I would like to use gpu to perform
this.

My problem is I have to iterate on iterable in reduce function to get my
values (each key contains a list of belong points). is there a way to build
an array directly? without use a loop? Maybe using a combiner.

Thank you for your time
