Subject: Re: Key-Value decomposition
Hi,
But i've only one RDD. Hre is a more complete exemple :
my rdd is something like ("A", "1;2;3"), ("B", "2;5;6"), ("C", "3;2;1")
And i expect to have
A",3) , ("B",2) , ("B",5) , ("B",6) , ("C",3) ,
("C",2) , ("C",1)
Any idea about how can i achieve this ?
Thank's

Very straightforward:
You want to use cartesian.
If you have two RDDs - RDD_1(³A²) and RDD_2(1,2,3)
RDD_1.cartesian(RDD_2) will generate the cross product between the two
RDDs and you will have
RDD_3((³A²,1), (³B²,2), (³C², 3))
