The main algorithm Betweeness.java is based on SimpleShortestPaths***.java.
In order to implement the new algorithm I had to override the message value
as well as the vertex value.
I dug up the examples, and the most compatible files where the files about
bracha-something calculation.
The overrided vertex value is myVertexValue.java and is based on
Bracha*Value.java and in there lies the problem I suppose, probably due to
misconfigurating the serializer
// Serialization functions -----------------------------------------------
@Override
public void readFields(DataInput input) throws IOException {
// this.distance=input.readLong();
this.sigma=input.readDouble();
// this.delta=input.readDouble();
}
@Override
public void write(DataOutput output) throws IOException {
int sz;
output.writeLong(this.distance);
output.writeDouble(this.sigma);
output.writeDouble(this.delta);
}
Of course, when I try to run the example I try to use the following
handler, that works for the simpleShortest paths, but now that I've
overriden the vertex value???
org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat
The main code of the project is on www.github.com/koutras/gb , to get
the whole idea...
At the moment Iam in a stalemate.... Any ideas so that I can make even a
small step are needed... Thanks..
