Subject Running Shortest Paths with edge list
Date Sat, 18 May 2013 17:00:35 GMT

I'm having trouble running the following example with a relatively small network edge list,
can someone please give me some hints on what I might be doing wrong?

> hadoop jar target/giraph-0.2-SNAPSHOT-for-hadoop-
org.apache.giraph.GiraphRunner org.apache.giraph.examples.SimpleShortestPathsVertex -if
-ip Relationships-Companies-FinancialOrg.tsv -of
-op shortestPathsOutputGraph -w 3

Exception in thread "main" java.lang.RuntimeException: class
