Return a value from Giraph master superstep

[Saliya Ekanayake]

Hi,

I am developing a graph algorithm where I need to do N invocations of
giraph. Each invocation will run some M number of supersteps. I need to
return a value from the last super step back to the main method before
invoking giraph. How can I do this?

For example, I have,

main(){

    for (int i = 0; i < N; ++i){
        // Create giraph conf
        // Create new Giraph runner
        ToolRunner.run(runner, ...)

        // I need to return a value here from this invocation.
    }
