because int different iter of numWalks, the graph should be reinitialized. \ p.s val (j, q) = GraphOps.setupAlias(clickNode.neighbors) val nextNodeIndex: PartitionID = GraphOps.drawAlias(j, q) clickNode.path = Array(vertexId, clickNode.neighbors(nextNodeIndex)._1) generates a random nextNodeIndex in graph init
