I use Spark in Java.
I want to access the vectors of RowMatrix M, thus I use M.rows(), which is
a RDDVector
I want to transform it to JavaRDDVector, I used the following command;
JavaRDDVector data = JavaRDD.fromRDD(M.rows(),
scala.reflect.ClassTag$.MODULE$.apply(Vector.class);
However, it
You can probably get around it with casting, but I ended up using
wrapRDD -- which is not a static method -- from another JavaRDD in
scope to address this more directly without casting or warnings. It's
not ideal but both should work, just a matter of which you think is
less hacky.
