> Affects Versions: 1.0.0
> Reporter: Wang Xu
> Priority: Minor

> In ShortestPath example, my input data is :(just edge input data)
> 1\t\3\11
> 1\t\5\12
> I run:
> hadoop jar
> giraph-examples-1.0.0-for-hadoop-2.0.0-cdh4.1.2-jar-with-dependencies.jar
> org.apache.giraph.GiraphRunner
> org.apache.giraph.examples.SimpleShortestPathsVertex -eif

> org.apache.giraph.io.formats.IdWithValueTextOutputFormat -eip
> /shortestPathsInputGraph -op /output-tmp/sp-37 -w 1 -ca
> SimpleShortestPathsVertex.sourceId=1 -ca giraph.zkList=dlxa107:2181
> Result is hadoop fs -cat /output-tmp/sp-37/*)
> 5 0.0
> 1 0.0
> 3 0.0
> Then i modify input dataļ¼(just edge input data)
> 1\t\3\11
> 1\t\5\12
> 3\t\3\0
