I am new with Giraph and I am willing to using it in my project. I am using hadoop 1.2.1. I builded giraph with mvn package -Phadoop_1.0 -Dhadoop.version=1.2.1 -DskipTests --offline. I ran the SimpleShortestPathsVertex example and all OK. With the same input I tried the SimplePageRankVertex example and failed:
This is the command I used: $HADOOP_HOME/bin/hadoop jar $GIRAPH_HOME/giraph-examples/target/giraph-examples-1.0.0-for-hadoop-1.2.1-jar-with-dependencies.jar org.apache.giraph.GiraphRunner org.apache.giraph.examples.SimplePageRankVertex -vif org.apache.giraph.io.formats.JsonLongDoubleFloatDoubleVertexInputFormat -vip /user/andro/input/tiny_graph.txt -of org.apache.giraph.io.formats.IdWithValueTextOutputFormat -op /user/andro/output/pagerank -w 1 This is the output: 13/10/09 14:21:36 INFO utils.ConfigurationUtils: No edge input format specified.

Maybe I did it wrong. Andro.
