In python or Spark In this problem you will need to modify the
graph so that there are no dead-ends. In particular you will
produce a file called graph.csv which is a collection of edges in
the graph such that none of the ending vertices of the edges are
dead ends. Note that after dropping dead-ends, new dead-ends may be
created and these will then need to be dropped. You may need
several rounds to produce the required file.
