Subject Re: Shortest Paths Example

Hi Rodrigo,

Looks like you need to change org.apache.giraph.lib -> .io

hadoop jar target/giraph-0.2-SNAPSHOT-for-hadoop-0.20.203.0-jar-with-dependencies.jar org.apache.giraph.GiraphRunner
org.apache.giraph.examples.SimpleShortestPathsVertex -if org.apache.giraph.io.JsonBase64VertexInputFormat
-ip shortestPathsInputGraph -of org.apache.giraph.io.JsonBase64VertexOutputFormat -op shortestPathsOutputGraph
-w 3


Giraph codebase moves fast, so documents are easily outdated.

Hope it helps,

~Jaeho
