I need a Java, Spark expert

Job ID: 33116917

Budget: $30 – $250 SGD

I need to convert a .osm file to graph in adjacency list format. I will also need to output the shortest path between two nodes (I need to include all the nodes in order from the source to destination node). More details in PDF. Also, Java knowledge alone is not enough, Spark knowledge needed as the program needs to be able to run for <20 min.
