From 90006f3c51f8cf9535854246050e27bb76b043f0 Mon Sep 17 00:00:00 2001 From: Alexander Ulanov Date: Tue, 28 Jul 2015 01:33:31 +0900 Subject: Pregel example type fix Pregel example to express single source shortest path from https://spark.apache.org/docs/latest/graphx-programming-guide.html#pregel-api does not work due to incorrect type. The reason is that `GraphGenerators.logNormalGraph` returns the graph with `Long` vertices. Fixing `val graph: Graph[Int, Double]` to `val graph: Graph[Long, Double]`.
