community detection on edges with weights on spark (louvain)

I would like to use Spark/graphx implementation of Louvain modularity algorithm. https://github.com/Sotera/spark-distributed-louvain-modularity

  1. Is there a way to apply it on a graph with weighted edges?

  2. It seems that an input file can contain 2 or 3 columns. If it is 2, then the first one is the source and the second is the destination. What is the third column? Weights?

Yes, you can apply it to weighted graphs and the third column is the edge weight.

Here you have a description of the expected data format.
