Updates any of the vertex values for those provided.
Updates any of the vertex values for those provided. Not all values must be replaced, and any extra vertices from the input RDD will be discarded. This is useful for setting the priors from a previous run or iteration of PageRank. Since this can cause the vector values to no longer be normalized, this will re-normalize the values after updating them.
